Every good chisel in my shop came from garage sales, flea markets or the
like. When you can get a whole handful for $10 it is definitely worthwhile.
I have old Bucks, Witherby and Swans that are as good as any new super duper
creation. The best ones came without handles. Chisel making is not rocket
science! Nor is tuning a chisel beyond anyone with a little patience.
Incidentally, all of my good chisels are socket firmers; I find the extra
length and weight helpful.
