A classic of the Counter-Strike series, the edge of this knife is press-fit Stellite perfectly held in place due to its precise fit with the titanium on the blade's cheek and spine. The handle is fossilized mastodon ivory held in a carbon fibre pocket. It has been given a forced patina using lemon and mustard dripped onto the surface.

A niche Classic Knife finish with strong conceptual appeal; the chemical patina on the original CS default knife suggests a weapon that has genuinely been in use since the earliest Counter-Strike matches. The blacklight reveal joke lands particularly well here.
