Compatible with most standard EDC folding knives, including most popular brands. Fits folders up to 5.5" in closed length.
Clean the outer shell with mild soap and water. For the foam interior, use a vacuum with a brush attachment to remove dust. Avoid storing open in direct sunlight for extended periods to maintain foam integrity.
PROTECT YOUR COLLECTION.
A dedicated spot for every blade
Stop leaving your premium steel loose together in a drawer. Our precision-cut foam ensures each knife stays separated. Preventing scratches and maintaining the perfect edge and blade integrity.
Adaptable to your growing collection
Not all knives are created equal. The removable insert in the top tray allows you to expand the compartment length when needed. Make room for those larger tactical folders or custom fixed blades that usually don't fit standard cases.
Secure in every scenario
The 331 provides a crushproof environment that shields your investment from drops, dust, and the unexpected.
