Yeah, but turn that octagon a few degrees around such that it doesn't align with that "OK" octagon shape of your hand, and it will turn into a pain. Literally.

Yeah and you don't hold a chisel in a textbook single-orientation way anyway in the real world. I can think of a few chiselling operations where in only five minutes one must adopt a good half-dozen different grips!

I'd want to be very sure that the handle was orientated correctly before buying anything with such a handle.

I'm a big fan of octagonal handles (of a completely different type) and yes, you do want to make sure of the alignment on a chisel.

It's a much different story with a turnscrew, which is why I feel the Best London Pattern Octagonal handle is a better fit for them (in a working tool, as opposed to a toolbox queen).
