I thought so.. to go that long and still be using the same handle stock, Shulin must have had a couple of truckloads stashed. I've got a few screwdrivers using the same stuff too. And it looks like the same forging dies and mandrels for the gouges. Just imagine the number of students beating on those things and trying to wear them out, and them still working after all those years.
So think of Ed Shulin's chisels as kind of a "secret handshake" ... you know about them only if you've been there.
I remember in my class we had a guy who got so obsessed with making his chisels that he never did get his stock done. Looking back those were a couple of the best years of my life.
I do envy you guys who kept up and stayed with it. I've always loved it and done a little but never to the levels I see here. Family and starvation took me on another route. But hey, it is what it is.
