Ok--here's another snath I picked up for the collection. No one would EVER want to use this monster for a real work tool, but it was too rare and fascinating to pass on. I've only ever seen the patent images for this model. Stupidly complex and doesn't even do its job well, but boy it sure is fun to look at!

Behold--the Seymour Vice Grip snath!
Good lord! What's that Transformers-looking contraption on the end?

It's a toothed plate designed to allow for adjustment of the lay of the blade, presumably without having to take a torch to your blade tangs. It doesn't work well, but more on that in a moment.

Nib shots. Note the interesting band construction--forged right from the rod itself and welded back on itself:

The curvature. Here's where we get into the crux of the problem. It has heavier curves than most Seymours of its period that I've seen, but they're a little backwards. Not enough curve on the fore-end and too heavily recurved in the back. It ends up sending the end of the snath nosediving towards the ground at a steep angle. As a result the adjustment mechanism helps correct for this sloppy bending but can't be adjusted far enough in order to actually bring the blade to a proper lay, defeating whatever minimal advantage the bulky mechanism might have tenuously provided.
Here it is laid against a pillar at the height/angle it would be if I were holding it. Note that in spite of being at maximum adjustment this blade still has about the same lay as I'd expect from an un-pitched blade mounted on a
well-bent simple snath.

One last beauty shot:
