Having a safety cutter as part of your gear is a small investment that offers a lot of peace of mind. We’re looking at both the Spinlock "S" Cutter Safety Knife and the Gill Harness Rescue Tool.
The Spinlock "S" Cutter Safety Knife comes in a small pouch that can be Velcro attached in a variety of places and can be relocated anytime. It has a lanyard that attaches to the pouch so you won’t lose it if dropped. It offers a very instinctual design when grabbing it to use.
The Gill Harness Rescue Tool is similar in design and comes with a lanyard that can be attached to any part of your gear as well as a “belt loop” sheath. This sheath is made to stay where you put it for the time being. The Gill Harness Rescue Tool also sports a shackle key which is always nice to have.
