This is one of Nick’s fancy tools. Normally titanium would be a terrible material to make a blade out of, because it’s quite soft (strong for its weight, but soft compared to steel). But this blade is a mix of titanium and ceramic powders, sintered together much like a diamond concrete saw. As such it is not particularly sharp. Instead it’s like a micro-serrated blade that abrades more so than it slices. Apparently it works really well, and because the titanium is soft, it slowly wares away, exposing new, sharp ceramic particles. (See the discussion of diamond saws in my book for more detail on this fascinating process.)
