I saw this article about chisels:
In the article, Chris Gochnour notes this for the best value Japanese chisel – the Grizzly:
“The end of the handle must be mushroomed over to set the hoop in place, so plan on 30 minutes per chisel for this task. “
I have a set of old Hirsch chisels I bought off of craigslist. They have a loose hoop around the end (presumably so the ends don’t split when struck with a mallet). The looseness has always bothered me, but I assumed the wood shrunk a bit. Should they be mushroomed, and if so how do you mushroom a chisel end?
