I have worked on this Karambit and just finished it up recently. The steel is from a TV stand and is 1/4 inch. It is most likely low carbon steel. I cut the steel's rough shape with and angle grinder and finished up with much file work. The bevel was done exactly the same. I tempered it with motor oil. The handle is an exotic Brazilian wood but i do not recall the name. I got it from a furniture shop through my uncle. The brass pins are 1/4 inch brass from the local hardware store. The sheath is leather from an old bag and is about 1/16 inch. I put it together with staples. I would have to estimate it took me 15 hours or so. Constructive criticism is most appreciated.
