Those are lather working tools, specifically the roller ends are stich markers that you trace along a pattern for a certain # stitch count. Ive also seen them used to transfer a chalk pattern to a soft material or fabric.
The larger wheel might be a perf cutter for leather as it kind-a looks sharpened, but I have never seen such an animal nor can I think of a reason to perf cut leather......just a bigger space stich count IMO
