The Armed Shark Sentinel is a full TC4 titanium balisong trainer engineered for serious flippers — premium strength-to-weight, silky bushing action, and set-and-forget consistency every session.

Built from TC4 titanium alloy handles paired with a 5-series stainless steel training edge, the Sentinel delivers a premium tactile feel that aluminum butterfly trainers simply can’t match. If you’re ready to level up your balisong flipping practice, this is it.
