Quoted text begins.(thanks George!), another tool you could try in addition to the skewed

End of quote.
The concept is fine, I have a lot of bent chisels, but the Hilti version
shown on that link worries me. It's intended for cutting out the joints in
brick for repointing, using a big hammer drill. It will cut out the joints,
and I'm sure it will also fracture and chip lots of the bricks around the
joints. Looking at the photo on the Hilti site, I expect that guy to blow
out big corners from the bricks. That's fine for the butcher masons who
then smear an inch wide swath of mortar and call that tuckpointing (you see
tons of that on old Chicago buildings, truly ugly work)... much safer for
that application is the Trow & Holden solution, with a special chisel and
an air hammer, so you can control the cut and stroke better.
A lot of masons here also use a 1/4" wide blade in a 4" angle grinder,
which tends to do a pretty sloppy job unless they are extremely careful.
Note I'm only talking about the application for which that Hilti tool
appears to be designed, not the original question of cutting recessed
relief work and detail work... the answers already given, and the use of a
miter chisel (skew chisel) are good solutions.
