except those under No. 9, which are short-handled chisels for small work.
The Japanese toolmakers fit these small chisels into a split handle as shown in fig. 5. The blade is held tightly in its place by the tapered ferrule when the handle is closed, or can be lengthened by opening the handle and pulling forward the blade in its slot. In this way the blade can be used down to its last inch.
3. MALLET
This is needed for driving the larger chisels.
