I've been using Lee Valley's magnetic corner chisel to clean up hinge
mortises, but I'm wondering if there is a larger version available -
something with a guide like the LV one, only larger, to handle the
radii left by larger diameter router bits. Anyone know of one?
Thanks.

There are right angle/90 degree chisels that you whack with a mallot or
hammer. Old school. ;~)

A bit more spendy. ;~(
