Details
When you need more working space and a blade with more substance, SATRE FX is the answer. It takes the essential design of the Satre and scales it up, improving control and cutting capacity without compromising its ergonomics. It is designed for continuous use, where the hand must not tire and the tool must remain predictable.
SATRE FX is a full-tang fixed blade with a skeletonized frame, designed to maintain good balance even during extended sessions. The more generous geometry offers a larger cutting surface and more stable handling during demanding tasks. The open construction also allows you to customize the handle with Paracord, adapting it to your preferences. The knife comes with a black Kydex sheath, pre-shaped and ready to use.
