Busse Battle Mistress that is. Technically, it's a CGFBM. Combat Grade Fusion Battle Mistress with Busse's Corrugated Bevel technology. This version was nicknamed the Mudsnake by those that got them. Not many in this incarnation. Muddy coating with Snakeskin micarta slabs. One of my personal favorites, along with one of my favorite rums, Sailor Jerry.
