Safe Practice. Realistic Feel. Built to Train Without Risk.

The Spyderco Endura 4 Trainer is a purpose-built folding knife designed for safe martial blade craft and handling drills. It features a blunt AUS-6 stainless steel blade with drilled holes to reduce weight and mimic the live version’s balance.

The red FRN handle with Bi-Directional Texturing™ ensures a secure grip, while the back lock mechanism and four-position pocket clip mirror the functionality of its sharpened counterpart. Drilled blade holes reduce weight and enhance balance, and the blunt edge with rounded tip keeps every drill safe. Ideal for instructors, students, and enthusiasts, this trainer lets you build muscle memory and confidence without the risk.
