Sharp things. Custom, production, different types of steels and heat treats, anything that has to do with edged tools and weapons. This one is one of my Grail pieces. Busse Combat Custom Shop one off Mojo, made with their proprietary INFI steel and heat treat. It doesn't follow the lines of the original production Mojos. It looks more like Busse's early Silent Knight, with the clip point. It also has custom G-Rex handles. It's very light, very fast, and very rad.
