Thanks. I. Sorby made mortising chisels ranging from 1/8" to 3/4". 10 in total. Mine are all Punch brand except the 3/4". I've been on the hunt for one of those for the last 10 years and I've never seen one. The one I have looks exactly like the rest of them, it just doesn't have the Mr Punch logo.
