Apparently, it's a knife brand from Solingen, but that's all I know; I've never seen the brand before.
This example is 4 inches closed and has a square tang (half-stop) on the oversized sheepfoot blade. Seem to be a Regular Jack pattern with extended bolster and oversized end cap. I also noted that it has a 'stove pipe kick' and great looking bone jigged covers. A very solid knife in great condition overall, and I'm curious if it is of 50's vintage or later; I believe 'Germany' would have been added after '64, but the stovepipe kick doesn't fit into the 50's picture.
Please, somebody enlighten me!
I really like this style of jigging. I have a Puma stockman in a similar style. It's a real shame that no U.S. makes attempts to duplicate it. Are you listening Bill Howard?
