I picked this up at a yard sale for ~$2 about 6 months ago and have been trying to figure out what the heck it is.

Any help would be greatly appreciated!

Not sure what this thing is

UPDATE 4/26/20 - added more pictures.

And yes, it does pivot - there seems to be a spring of some sort in there.

UPDATE 4/27/20

While there doesn't seem to be complete understanding, it sounds like a double marking gauge of some sort. I appreciate everyone's assistance on this! I'll have to figure out if it's worth me trying to understand it, or repurpose the pieces into something more interesting!

  • Oh Goody. another, what tool is this question. I think marking gauge of some kind. More photos please, Especially of the little metal nubs on the ends.

  • We could do with further pics. From the single image it looks like the two bars are connected by a pivot at the top, but that could be an accident of placement and I can't imagine how that would work. And what's in the small plastic container, are they blades of some sort? If they are do they have a 90° bend near one end? It kinda looks like they do in the photo but I don't know if I'm just talking myself into seeing that and can't figure how they're held.

  • I had sort of imagined the blades to slot in... kinda like this: amazon.ca/Marking-Gauge-Nihon-Sao-Kebiki/dp/B07G4C6SDX . To the OP: do the shiny things at the end tighten to lock the blades? Apr 26 '20 at 18:05
  • Hey all - added more pictures. @Graphus - they do pivot at the top. Yes, double sided blades.

    @AloysiusDefenestrate - they do tighten where I would imagine blades would go

I'm going to call that a double marking gauge.

Double because it looks like you can separate the two rods and set them independently. (Useful for marking independent sides of a mortise, for example.)
