Primitive Marking gauge ?

[bilspe]

Looks like some kind of marking gauge.
Very early, made of oak
Has a sawtooth pattern on the cutter
Any ideas anyone ?

Whoops,,,, that would be a good idea ?

Looks like it would leave quite a thick line, could it be to start a saw cut line that you then follow with handsaw?

Interesting tool , I have never seen anything like this .

It has similarities to a coopers croze for putting the groove around the inside of a barrel?

Size of those teeth it would be hard to drag along wood and get a clean cut. Wondering if it may be a stone masons gauge. Has a home made look to it.

The cutting teeth are curved convex, so the middle of the blade would cut deeper on a flat surface than the front of back. That supports the idea of using it on a convex surface, where it would produce a uniform cut.

In the first photo, showing a close up of the teeth, the cutting blade and holder looks to have been rotated 90 degrees anticlockwise in the handle to its normal position of use. You can see curved witness/wear marks on the handle, supporting running on a curved surface. That would also make sense, as you would pull outwards on the handle in order to make the blade dig into the material.
