Lutz file handle W/ Stanley

[HeelSpur]

Picked this up for a buck but its mis-matched, is this meant to be like this,
or is it just a homemade rig?

Just guessing, that looks like a counter sink, for recessed head woodscrews.   If one were to pull the toolhead out of the handle, one would find it was originally a square tapered shank tool, cut off and shoved into the Lutz handle.   Interesting application, makes you wonder what his goal was when he fabricated it.

Not having to walk from the bench to the drill press, or not having to stand up to use the brace.  Maybe relieving the edges of a hole to ease in a dowel?

The countersink is hard enough you could reasonably use it for deburring holes in brass or such....

It's an old idea: handy for countersinking one or two holes in softwood, or breaking the edges on a hole to remove splinters.  You can buy one brand new, such as from the website below, or you can whittle your own.  I've got one I whittled myself, also from a file handle (although I put a power drill chuck in a "cut threads on your file tang" handle, which is conveniently 3/8"-24, the same as the spindle on most 1/4" power drills, then the countersink into that).
