Unknown Tool

I got this tool in an estate, and do not have many good ideas about what it is.  It may be some kind of holdfast or a scribe.  I have an extra metal piece with it that has not been drilled out yet.

Looks like the sort of home made tool a stone mason would have used - a sort of marking gauge for scribing lines parallel to an edge - many wood working tools (e.g. bevels or squares)  had an equivalent for stone masons, but often they also had steel bodies.. But I guess a wooden body would serve just as well, although it would wear out faster... This one shows considerable wear on one face, consistent with being used on stone...

The approximately 45 degree recess on the worn looking side appears to have been cut into it with a chisel rather than worn into it from use.
