The IST Sports Squeeze-Lock Dive Knife K27 is designed for ease of use and secure handling underwater. Its innovative squeeze-lock handle allows divers to release the knife from its sheath simply by gripping the handle—disengaging the locking mechanism—while releasing the grip reengages the lock for secure storage.

This intuitive system enables quick, one-handed deployment and replacement, making it especially useful in emergency situations. The dual-edge blade is constructed from corrosion-resistant 420J2 stainless steel and features a smooth cutting surface, serrated edge and integrated line cutter for added versatility.

Built for reliability and convenience, the K27 is a practical addition to any diver’s gear setup.
