I needed a mortising chisel, but got sticker shock when pricing them. Old ‘pigsticker’ things on e-bay were going for $30 or so not including shipping, and new mortising chisels were nearly $50! I had a $2 bargain bin pry bar from the hardware store with a square shank. I cut off the business end at an angle. A bit of grinding, and few strokes on a fairly course stone and viola!
I was pleasantly surprised on how serviceable the steel is. I don’t think the steel would be any good for a fine paring chisel but seems to work fine here. I’ve also abused the handle pretty well, pounding it with an iron hammer. so far no problems.
