Thread: Manufacturer ID

Howdy Gents,
This blade says Guaranteed XLNT.
I found info on the manufacturer Wadsworth XLNT.
But no threads on "Guaranteed" XLNT.
Also this blade has a swaged concave grind (or what ever it's called) on the front blade face making it shoulderless on the front but not on the back.

Anyway, it doesn't seem German to me. Wadsworth was in Germany right?
It has a crown too.
Celluloid scales are not original, I would say.
Any info? Anybody else use XLNT besides Wadsworth?

Thank you and have a great day!
