A '''hand plane''' is a [[tool]] for shaping [[wood]] using [[muscle power]] to force the cutting blade over the wood surface. Some rotary '''power planers'''<!-- term redirects here ---> are motorized [[power tools]] used for the same types of larger tasks, but are unsuitable for fine-scale planing, where a miniature hand plane is used.

Generally, all planes are used to flatten, reduce the thickness of, and impart a smooth surface to a rough piece of [[lumber]] or timber. Planing is also used to produce horizontal, vertical, or inclined flat surfaces on workpieces usually too large for shaping, where the integrity of the whole requires the same smooth surface. Special types of planes are designed to cut [[Woodworking joints|joints]] or [[Molding (decorative)|decorative mouldings]].

Hand planes are generally the combination of a cutting edge, such as a sharpened metal plate, attached to a firm body, that when moved over a wood surface, take up relatively uniform shavings, by nature of the body riding on the 'high spots' in the wood, and also by providing a relatively constant angle to the cutting edge, render the planed surface very smooth. A cutter that extends below the bottom surface, or '''sole''', of the plane slices off shavings of wood. A large, flat sole on a plane guides the cutter to remove only the highest parts of an imperfect surface, until, after several passes, the surface is flat and smooth. When used for flattening, bench planes with longer soles are preferred for boards with longer longitudinal dimensions. A longer sole registers against a greater portion of the board's face or edge surface which leads to a more consistently flat surface or straighter edge. Conversely, using a smaller plane allows for more localized low or high spots to remain.

Though most planes are pushed across a piece of wood, holding it with one or both hands, [[Japanese plane]]s are pulled toward the body, not pushed away.

[[Woodworking machinery]] that perform a similar function as hand planes include the [[jointer]] and the [[thickness planer]], also called a thicknesser; the job these specialty power tools can still be done by hand planers and skilled manual labor as it was for many centuries. When [[lumber|rough lumber]] is reduced to [[dimensional lumber]], a large [[electric motor]] or [[internal combustion engine]] will drive a thickness planer that removes a certain percentage of excess wood to create a uniform, smooth surface on all four sides of the board and in specialty woods, may also plane the cut edges.

Hand planes are ancient, originating thousands of years ago. Early planes were made from wood with a rectangular slot or [[Mortise and tenon|mortise]] cut across the center of the body. The cutting blade or iron was held in place with a wooden wedge. The wedge was tapped into the mortise and adjusted with a small [[mallet]], a piece of scrap wood or with the heel of the user's hand. Planes of this type have been found in excavations of old sites as well as drawings of woodworking from medieval Europe and Asia. The earliest known examples of the woodworking plane have been found in [[Pompeii]], although other [[Ancient Rome|Roman]] examples have been unearthed in [[Roman Britain|Britain]] and [[Germania|Germany]]. The Roman planes resemble modern planes in essential function, most having [[iron]] wrapping a wooden core top, bottom, front and rear, and an iron [[blade]] secured with a [[Wedge (mechanical device)|wedge]].  One example found in [[Cologne]] has a body made entirely of [[bronze]] without a wooden core.<ref>C. W. Hampton, E. Clifford (1959). ''Planecraft''. p. 9. C. & J. Hampton Ltd.</ref> A Roman plane iron used for cutting [[Molding (decorative)|molding]]s was found in [[Newstead, Nottinghamshire|Newstead]], England.<ref>Mercer, Henry C. (1975). ''Ancient Carpenters' Tools''. p. 16. [[Bucks County, Pennsylvania]]: Bucks County Historical Society.</ref> Histories prior to these examples are not clear, but furniture pieces and other woodwork found in [[Egypt]]ian tombs show surfaces carefully smoothed with some manner of cutting edge or scraping tool. There are suggestions that the earliest planes were simply wooden blocks fastened to the soles of [[adze]]s to effect greater control of the cutting action.

In the mid-1860s, [[Leonard Bailey (inventor)|Leonard Bailey]] began producing a line of cast iron-bodied hand planes, the patents for which were later purchased by Stanley Rule & Level, now [[Stanley Black & Decker]]. The original Bailey designs were further evolved and added to by [[Justus Traut]] and others at Stanley Rule & Level. The Bailey and [[Bedrock plane|Bedrock]] designs became the basis for most modern metal hand plane designs manufactured today. The Bailey design is still manufactured by Stanley Black & Decker.{{cn|reason=originally claimed for Stanley but the company no longer exists|date=June 2024}}

In 1918 an air-powered handheld planing tool was developed to reduce shipbuilding labor during World War I. The air-driven cutter spun at 8,000–15,000 rpm and allowed one man to do the planing work of up to fifteen men who used manual tools.<ref>{{Cite magazine |url=https://books.google.com/books?id=EikDAAAAMBAJ&pg=PA68 |title=Planing Ship Timbers with Little Machines |magazine=Popular Science |volume=93 |issue=6 |issn=0161-7370 |date=December 1918 |publisher=Bonnier Corporation |language=en}}</ref>

Modern hand planes are made from wood, [[ductile iron]] or [[bronze]] which produces a tool that is heavier and will not rust.

[[File:Bench plane iron.jpg|thumb|A modern milled chipbreaker secured atop a bench plane iron]]

The standard components of a modern, Western-style hand plane include:
{{ordered list |type=upper-alpha
| '''mouth''': an opening in the sole of the plane through which the blade extends, and through which wood shavings rise.
| '''iron''': a steel blade which cuts the wood.
| '''lever cap''': secures the cap iron and iron firmly to the frog.
| '''depth adjustment knob''': controls the cutting depth of the iron.
| '''knob''': allows a second hand to guide the plane.
| '''cap iron''' or '''[[chipbreaker]]''': reinforces the iron and curls and breaks apart wood shavings as they pass through the mouth.
| '''lateral adjustment lever''': skews the iron so that the depth of cut is uniform across the mouth.
| '''tote''': the principal handle for gripping the plane.
| '''cam lever''': pivots a sliding section of the forward end of the sole to adjust the gap in the plane's mouth.  It is anchored to the threaded post of the knob and secured by tightening the knob.
| '''frog''': an adjustable iron wedge that holds the plane iron at the proper angle and allows it to be varied in depth relative to the sole. The frog is screwed down to the inside of the sole through two parallel slots and on many planes is only adjustable with a screwdriver when the plane iron is removed. Some planes, such as the [[Stanley Black & Decker|Stanley]] [[Bedrock plane|Bedrock]] line and bench planes made by [[Lie-Nielsen Toolworks|Lie-Nielsen]] and WoodRiver/[[Woodcraft Supply|Woodcraft]], have a screw mechanism that allows the frog to be adjusted without removing the blade.
| '''sole''': the bottom face of the plane.}}

== Types ==
[[File:Veritas router plane.jpg|thumb|[[Router plane]]]]

Most planes fall within the categories (by size) of  '''[[block plane]]''', '''[[smoothing plane]]''', and '''jointing plane'''. Specialty planes include the [[shoulder plane]], [[router plane]], [[bullnose plane]], and '''chisel plane''', among others.

Electrically powered '''hand planers''' (loosely referred to as '''power planes''') have joined the hand-held plane family.

Bench planes are characterized by having their cutting bevel facing down and attached to a chipbreaker. Most metal bench planes, as well as some larger wooden ones, are designed with a rear handle known as a tote. Block planes are characterized by the absence of a chipbreaker and the cutting iron bedded with the bevel up. The block plane is a smaller tool that can be held with one hand and that excels at working across the grain on a cut end of a board (end grain). It is also good for general purpose work such as taking down a knot in the wood, smoothing small pieces, and [[chamfer]]ing edges.

Different types of bench planes are designed to perform different tasks, the name and size of the plane being defined according to its use. Bailey iron bench planes were designated by number with respect to the length of the plane. This has carried over through the type, regardless of manufacturer. A No. 1 plane is but little more than five inches long. A typical smoothing plane (approx. nine&nbsp;inches) is usually a No. 4, jack planes at about fourteen&nbsp;inches are No. 5, an eighteen-inch [[fore plane]] will be a No. 6, and the jointer planes at twenty-two to twenty-four inches in length are No. 7 or 8, respectively. A designation, such as No. 4{{frac|1|2}} indicates a plane of No. 4 length but slightly wider. A designation such as 5{{frac|1|2}} indicates the length of a No. 5 but slightly wider (actually, the width of a No. 6 or a No. 7), while a designation such as 5{{frac|1|4}} indicates the length of a No. 5 but slightly narrower (actually, the width of a No. 3). "Bedrock" versions of the above are simply 600 added to the base number (although no "601" was ever produced, such a plane is indeed available from specialist dealers; 602 through 608, including all the fractionals, were made).

=== Order of use ===
[[File:Stanley transitional jointer plane.jpg|thumb|right|Stanley No. 32 transitional jointer plane (26 inches long)]]
[[File:Kanna2.gif|frame|A Japanese plane in use]]

A typical order of use in flattening, truing, and smoothing a rough sawn board might be:
* A '''[[scrub plane]]''', which removes large amounts of wood quickly, is typically around {{convert|9|in|mm}} long, but narrower than a smoothing plane, has an iron with a convex cutting edge and has a wider mouth opening to accommodate the ejection of thicker shavings/chips.
* A '''[[jack plane]]''' or '''[[fore plane]]''',<ref name=pw>{{Cite web|url = https://www.popularwoodworking.com/tools/understanding_bench_planes|title = Understanding Bench Planes|date = 14 February 2019|access-date = 29 April 2018|archive-date = 30 April 2018|archive-url = https://web.archive.org/web/20180430114047/https://www.popularwoodworking.com/tools/understanding_bench_planes|url-status = live}}</ref> usually between {{convert|14|and|20|in|mm}} long, is also used for initial material removal, but with more accuracy and flattening capability than the scrub.  
* A '''[[jointer plane]]''' is between {{convert|22|and|30|in|mm}}<ref name=pw/> long, and is used for jointing and final flattening out of boards.
* A '''[[smoothing plane]]''', up to {{convert|10|in|mm}} long, is used to begin preparing the surface for finishing.
* A '''polishing plane''' (''[[Japanese plane|shiage ganna]]'') is a traditional Japanese plane designed to take a smaller shaving than a Western smoothing plane to create an extremely smooth surface. Polishing planes are the same length as western smoothing planes, and unlike Western planes, which are pushed across a board, is pulled with both hands towards the user.

=== Material ===
Planes may also be classified by the material of which they are constructed:
* A '''wooden plane''' is entirely wood except for the blade. The iron is held into the plane with a wooden wedge and is adjusted by striking the plane with a hammer.
* A '''transitional plane''' has a wooden body with a metal casting set in it to hold and adjust the blade.
* A '''metal plane''' is largely constructed of metal, except, perhaps, for the handles.
* An '''infill plane''' has a body of metal filled with very dense and hardwood on which the blade rests and the handles are formed. They are typically of English or Scottish manufacture. They are prized for their ability to smooth difficult grained woods when set very finely.
* A '''[[side-escapement plane]]''' has a tall, narrow, wooden body with an iron held in place by a wedge. They are characterized by the method of shaving ejection. Instead of being expelled from the center of the plane and exiting from the top, these planes have a slit in the side by which the shaving is ejected. On some variations, the slit is accompanied by a circular bevel cut in the side of the plane.

=== Special purposes ===
[[File:Stanley Plane 92 (3).jpg|thumb|Stanley No. 92 [[rabbet plane]]]]
[[File:Stanley Plane 78 (5).jpg|thumb|Stanley No. 78 fillister plane]]
[[File:Fingerhoevle.jpg|thumb|Finger planes. Note the size.]]
[[File:Stanley 55 01.jpg|thumb|Stanley No. 55 combination plane]]

Some special types of planes include:
* The '''[[rabbet plane]]''', also known as a rebate or openside plane, which cuts rabbets (rebates) i.e. shoulders, or steps.
* The '''[[shoulder plane]]''', is characterized by a cutter that is flush with the edges of the plane, allowing trimming right up to the edge of a workpiece. It is commonly used to clean up dadoes (housings) and tenons for joinery.
* The '''[[fillister plane]]''', similar to a rabbet plane, with a fence that registers on the board's edge to cut rabbets with an accurate width.
* The '''[[moulding plane]]''', which is used to cut mouldings along the edge of a board.
* The '''[[grooving plane]]''' which is used to cut grooves along the edge of a board for joining. Grooves are the same as dadoes/housings but are being distinguished by running with the grain.
* The '''[[plow plane|plow/plough plane]]''', which cuts grooves and dadoes (housings) not in direct contact with the edge of the board.
* The '''[[router plane]]''', which cleans up the bottom of recesses such as shallow mortises, grooves, and dadoes (housings). Router planes come in several sizes and can also be pressed into service to thickness the cheeks of tenons so that they are parallel to the face of the board.
* The '''[[chisel plane]]''', similar to a bullnose plane, but with an exposed blade which allows it to remove wood up to a perpendicular surface such as from the bottom inside of a box.
* The '''[[finger plane]]''', which is used for smoothing very small pieces such as toy parts, very thin strips of wood, etc. The very small curved bottom varieties are known as violin makers planes and are used in making stringed instruments.
* The '''[[bullnose plane]]''' has a very short leading edge, or "toe", to its body, and so can be used in tight spaces; most commonly of the shoulder and rabbet variety. Some bullnose planes have a removable toe so that they can pull double duty as a chisel plane.
* The '''combination plane''', which combines the function of moulding and rabbet planes, which has different cutters and adjustments.
* The '''circular''' or '''{{Vanchor|compass plane}}''', which utilizes an adjustment system to control the flex on a steel sheet sole and create a uniform curve. A concave setting permits great control for planing large curves, like table sides or chair arms, and the convex works well for chair arms, legs and backs, and other applications. The compass plane, which has a flexible sole with an adjustable curve and is used to plane concave and convex surfaces. Typically used in wooden boat building.
* The '''[[toothed plane]]''', which is used for smoothing wood with irregular grain.<ref>{{cite web|title=Toothed Plane|url=http://www.fine-tools.com/G301211.htm|publisher=ECE|access-date=2014-12-11|archive-url=https://web.archive.org/web/20140707173426/http://fine-tools.com/G301211.htm|archive-date=2014-07-07|url-status=dead}}</ref> and for preparing stock for traditional hammer veneering applications.
* The '''[[spill plane]] ''' which creates long, spiraling wood shavings or tapers.
* The '''[[spar plane]]''', which is used for smoothing round shapes, like boat masts and chair legs.<ref>{{Cite web|url=http://forum.woodenboat.com/showthread.php?144707-Shaping-plane-for-rounding-a-spar|title=Shaping plane for rounding a spar|date=March 4, 2012|website=The WoodenBoat Forum|access-date=December 11, 2014|archive-date=March 4, 2016|archive-url=https://web.archive.org/web/20160304052819/http://forum.woodenboat.com/showthread.php?144707-Shaping-plane-for-rounding-a-spar|url-status=live}}</ref>

* Hollows and rounds are similar to moulding planes, but lack a specific moulding profile. Instead, they cut either a simple concave or convex shape on the face or edge of a board to create a single element of a complex-profile moulding. They are used in pairs or sets of various sizes to create moulding profile elements such as fillets, coves, bullnoses, thumbnails ovolos, ogees, etc. When making mouldings, hollows and rounds must be used together to create the several shapes of the profile. However, they may be used as a single plane to create a simple decorative cove or round-over on the edge of a board. Many of these hollows and rounds can be classified in the category of side-escapement planes.

== Use ==
[[File:With-against-grain-en.svg|thumb|Planing ''with the grain'' and ''against the grain'']]

Planing [[wood]] along its side [[wood grain|grain]] should result in thin shavings rising above the surface of the wood as the edge of the plane iron is pushed forward, leaving a smooth surface, but sometimes splintering occurs. This is largely a matter of cutting ''with the grain'' or ''against the grain'' respectively, referring to the side grain of the piece of wood being worked.

The grain direction can be determined by looking at the edge or side of the work piece. Wood fibers can be seen running out to the surface that is being planed. When the fibers meet the work surface it looks like the point of an arrow that indicates the direction. With some very figured and difficult woods, the grain runs in many directions and therefore working against the grain is inevitable. In this case, a very sharp and finely-set blade is required.

When planing ''against the grain'', the wood fibers are lifted by the plane iron, resulting in a jagged finish, called '''tearout'''.

Planing across the grain is sometimes called traverse or transverse planing.

Planing the end grain of the board involves different techniques and frequently different planes designed for working end grain. Block planes and other bevel-up planes are often effective in planing the difficult nature of end grain. These planes are usually designed to use an iron bedded at a low angle, typically about 12 degrees.
