what chisel shape would you choose.. *PIC*

..if you could make chisels and weren't limited by designs that could be easily made by machine.

I've experimented in the last week or two with chisels that have some curvature on the back - at first because I wanted some favorable bias in case warpage occurred in heat treatment, but with some experimentation, I've got that down to a small amount.

I like that the moderate curvature seems to counter movement of the chisel down into a moderate cut, but for paring, it would take some getting used to. inevitably, what happens is that you flatten some segment of the chisel when working the back (and I have most of the curvature up in the neck of the chisel with less of the relief toward the end). For a chisel that's intended to be used for heavier work (on its bevel side) it wouldn't be that great.

The other aspect I've come to have some preference for is a bit of taper in width. This is a favorable thing for making, I guess, though making a chisel that was parallel sided when filing to size wouldn't be very difficult. It's also favorable in using (no real side grip from the chisel in a cut).

The last aspect that I like is less heft in a chisel used for cutting joints - if the business end is kept relatively thin with strength closer to the ferrule, the chisel can be lifted and moved without any thought. The fact that it's less bulky at the end is nice for grinding and sharpening purposes, too.
