Bayou Custom Sheath is a full service kydex sheath maker meaning they make sheaths for a ton of different knives and tools. I became aware of them when I was searching for a more compact bit cover for my RMJ Tactical Jenny Wren Tomahawk.
The Jenny Wren, like all RMJ Tactical Tomahawks, comes with their excellent sheath system but I was looking for something a bit more compact since I often carry the Jenny Wren in a pack. Bayou Custom Sheaths had just what I was looking for and even had a TAD Edition Jenny Wren like mine to mold the sheath.
Their bit cover is a simple fold-over design with 3 eyelets to prevent the cutting edge from coming though the sheath. It leaves the hammer pole exposed for use and features a shockcord retention strap to ensure the bit cover stays put even if it is wallowing around in your day pack.
