We did some mods for our friend Josh over at The Gray Bearded Green Beret channel and proprietor of The Flint & Steel bush craft and survival training group. Check out his previous initial impressions video here.
The "GBGB" modification entails us sharpening the edges on the spine and butt of the knife for ferro rod use and flattening out the hand retaining swell on the but of the knife for easier one handed use when your arm and hand have been injured. Its a completely free modification anyone can choose at checkout and seems so far to be extremely popular.
