Size:  12.4 KBI've been thinking about how the J Rodgers craftsman did this and am interested in others opinions.

As for the Mfg Info - I think it was burned or seared in with a hot brand. Under the scope it looks like other samples I have where folks got crazy with the 'hot pin test.'

As for the tangway - I think the way was bored out with a round drill bit, then squared with a tiny scraper. I haven't thought of another way to put a rectangular hole in ivory- I imagine a flat, stiff wire with sharpened hook end. Not the best pic, but you can see the way is off-center. The tang is also off-center relative to the blade the same degree, so the craftsman skillfully squared the tangway to match.

Its a greater shaver. I've got a microfastener at pivot for now so I can take apart and inspect.
