The work of the chisel can be divided into two types - chisel and chipping. Different chisels are used for different purposes.
Oblique chisel - the most commonly used, mainly used to repair dead corners or joint surfaces of wood.
Flat chisels - have a thinner and longer blade than a bevel chisel and are mainly used to smooth the bottom surface or remove some small sawdust.
Mortise Chisel - Large section blade and thick chisel shank, mainly used for mortising.
Bevel chisel - a type of bevel chisel with a sloping edge that can easily reach dead ends and is used for chamfering or grooving.
A chisel is one of the commonly used tools in woodworking. Whether the chisel works well or not depends mainly on the quality of the sharpening edge. After the chisel is ground, the middle of the chisel blade should be concave, in the shape of a crescent, and the depth of the concave is generally 1-1.5mm.
Some woodworkers also know the requirements mentioned above, but they cannot meet the standard during the specific grinding process, and sometimes they may be ground into a protruding crescent shape. Some people had to make a deep groove in the middle of the chisel blade first. This way the chisel blade is neither sharp nor unsightly, and there are problems such as difficulty in removing slag.
