Woot!
I think this is preferable. However, I’d be willing to bet that most of the time people just pick up a precision chisel, and only use the basic one for specialized/large builds. One corner at a time isn’t too onerous, even for stairs.
I think, however, only having a precision chisel may be a better option. It stays more consistent w/ regular chisels, and simplifies things a bit.
One crazy idea for a “advanced chisel” might be chisel templates: Craft a chisel template tool, put it into a “record” mode, whack a block w/ the chisel configuration you like, and then each block it hits from then on would immediately chisel into that configuration. Hold onto multiple chisel templates for all your building needs.
(or maybe two items rather than a modal item - one for recording, one for cutting? not sure what works best w/ the current implementation)
