In my post on tool handles/holders
I purposefully did not mention a very interesting and useful
at first glance appears to be a hand vise.
But it is also a bitstock tool that came with a set of tools,
including a washer cutter, in a compartment in its handle.
It was made by Miller's Falls and appeared to be popular in the
1920's. It was referred to as "No. 1 Alford's Hand Vise" and
catalog illustrations show it and its tools.
But wait, there's more! Several other manufacturers made similar
tool holders that fit in a brace and I include photos of them in
this post. Captions are with each photo.
If you have a Starrett or Goodell Pratt hand vise, pull hard on
the handle. My guess is that there will be a bitstock tang
inside that was there all along and you didn't know it.
This photo shows this tool as it is usually found. More often
than not there
are no, or very few, tools in the handle and nothing is in the
hole in the vise frame.
This is a detail of an illustration of this tool in a 1920's
Miller's Falls catalog.
This detail of the catalog illustration shows the handle and
as the washer cutter.
