@russ A little birdie once told me that Elmer does indeed make some tools for stewmac.

@mattbeels. Good to know Matt.

Cheers @boo.
Looking a little more into it. I think Elmer may be a Chinese manufacturer who probably do supply Stewmac with certain tools. The Fret Slotting Jig appear identical.

Hey @boo. Do you know if the Elmer tools on the glued to music site are made by the same people who make the Stewmac tools? They look very similar. 🤔
