Wide jointer plane comprised of three parts, a long rectangular wooden body with an angled cutout through the middle, a wood handle on the heel and a leather strap on the toe (a), a wide wooden wedge with two longer pieces of wood on either edge (b), and a thin iron with a flat blade at the bottom (c). The wedge and the iron fit together inside of the plane's body, and the wedge holds the iron in place as it cuts the wood below the plane. Stamped on both the toe and the heel of the plane is "I BLOWER".
The jointer plane, also known as the try plane or trying plane, is a type of hand plane used in woodworking to straighten the edges of boards in the process known as jointing, and to flatten the faces of larger boards. Its long length is designed to 'ride over' the undulations of an uneven surface, skimming off the peaks, gradually creating a flatter surface. In thicknessing or preparing rough stock, the jointer plane is usually preceded by the fore plane or jack plane and followed by the smoothing plane. The use of the name jointer plane dates back to at least the 17th century, referring to the process of readying the edges of boards for jointing. The terms try plane, trying plane, and trueing plane have been in use since at least the 19th century. As with other hand planes, jointer planes were originally made with wooden bodies. But, since the development of the metal-bodied hand plane at the end of the 19th century, wooden-bodied jointers have been largely superseded. Metal-bodied planes are heavier, which is particularly noticeable for planes as large as jointers. This can make metal-bodied jointers more tiring to use for extended periods of time.
