SPYDERCO BUG KNIFE

The Bug, by
Spyderco, is a fully functional slip-joint folding knife in an
incredibly tiny package. When closed, the micro-sized knife is not much
larger than a paper clip, and although small, it offers reliable high
performance from its teensy high-carbon stainless steel, razor sharp
blade (take a look at the insanely happy Amazon reviews). The keychain
knife features a very strong slip joint that keeps it rigid during
cuts, and has a lanyard hole to accommodate a chain or a key ring.
