Unique Made in Germany Fixed Blade Knife.
The top of this blade looks like a saw blade.
Overall length is around 6.5" with the blade at 3.75".
"Made in Germany" is on one side of blade. The other side appears to have the letters STFPE. Cannot find any information on this knife.
I believe this fixed blade knife is very old. The bone handle has been riveted onto the blade. Very unusual.
