263974 <gtgrouch@r...> 2017‑11‑16 Re: Protuberance on chisel (upper ferrule)
I've never purchased a chisel with schlagring where there was not wood
protruding past the metal at the strike end.

The only chisels with a true metal striking surface are the ones like the
Stanley everlast design.

I agree that the cheap loose metal bands you see occasionally should be
discarded immediately: they're useless.

I think there is something to be said for the term "upper ferrule" for the half-
assed imitation of a hoop (the correct English-language term for what Germans
call a "schlagring") on these inexpensive chisel handles. A proper hoop is a
solid, heavy-duty iron ring shrunk or press-fitted into place, able to withstand
long-term battering from a steel hammer. A thickness of 1/8" is not unusual,
certainly more than 1/16" for examples that actually do a job. The modern "upper
ferrule" is made of thin stamped steel fitted loosely and held in place by a
dimpled spot, utterly without function and unable to withstand any degree of
impact at all. Better be rid of an upper ferrule right away. And I would save
the traditional terms for traditional parts that serve a function.
