The first one here is a loop knife forged from a single loop of 3/8" square bar.
The one being held is a cable damascus knife I forged on the set of The Postman movie.
The group shot is the largest single sale I ever made of knives. They were sold to a dealer. Most of the knives in the lot were of a design I came up with that was very popular with historical re-creationists since it fits in all time periods from 500 to 1900 AD.
