As Mike has mentioned, tang handles are generally easy to make and fit. The advantage of tanged chisels is that they have lighter blades, which improves feedback. I have also made many socket chisel handles, and do not hesitate to add a dab of epoxy. A little heat (from a hairdryer or heat gun) will soften and loosen this if you wish to replace the handle.

Japanese chisels (and Western chisels, such as the Veritas and Blue Spruce) use a combined tang and socket.
