The author describes the process of creating a unique folding knife inspired by a YouTube video. Since the original author didn't provide a drawing, they used a sketch from the video to create their own design.
The author made the knife handles from fiberglass G10, a durable composite material, using epoxy resin and glass mat. They encountered a setback when the resin crystallized prematurely due to overheating, but were able to re-mix the composition.
For the blade, they used a kitchen hatchet made of hardened stainless steel, which they cut and ground to the desired shape. They created descents on the blade using a grinder and sandpaper, achieving a razor-sharp edge.
The author also created a spacer with an eyelet for a lanyard from a rejected blade. Before assembling the knife, they sharpened the blade using a sharpener and polished it with stones.
The final assembly involved grinding cap nuts into small pins, cutting an axial screw from a furniture tie, and using copper washers and countersunk screws. The author used an INCO cordless screwdriver to tighten the screws.
The finished knife has a pleasant mechanism, cuts perfectly, and has a well-spring-loaded blade in the closed position. The author achieved a good balance in the center of the knife, making it ideal for use in various situations.
