I was using my Marples mortising chisel and my hand caught a sharp edge. I looked and the brass ferrule was cracked - full thickness and along the whole length. Well, that wouldn’t do!! I grabbed a small piece of one inch left over brass round stock and turned a new thicker, better ferrule on my metal lathe and made the chisel better than new.
The whole project took about an hour - from me noticing the issue until the repaired chisel went back in the roll.
