Many many thanks for all the replies.
My inquiry stemmed from a tool I saw in a barn (stacked full of tools freshly
orphaned, but that’s another ongoing story)
The tool was quite thick, maybe even 1/2in. It had a bench froe configuration,
handle in line with the “blade”.
And what a blade it was. 1/2in thick, maybe 2.5in wide, one side double bevelled
(NOT a bezel, remember those days??) all the way down, and the other side double
bevelled 3/4 of the way down the 6in blade, but the final 1 1/2in was completely
un-bevelled, just squared off.
I assume *that* part at the end was where hammering was done. Neither edge
particularly sharp. Perhaps even “dull as a froe”.
Wish I had a picture, but alas, my mind was swimming with thoughts of how all of
these tools were going to get sold. Nobody knows yet!
