Here is a little something different. Karambits are fun, but I personally prefer an edge in orientation, with a double edge for something extra.
This one is 1/8" O1 tool steel
2.5" blade tip to scale and about 6.75" OAL
The knuckle duster is pretty cool and really has me thinking of making a full blown trench knife
The next one of these I make will have a straight blade like my standard pikal.
