Sailor's tool with locking stainless steel 2" blade. One hand operation, use thumb knobs to open and use thumb to press against lock to close. Carry in the included pouch while ashore, and clip to a strap on your life jacket for ready use while aboard your boat. Interestingly enough, two of our staff were independently looking into a new knife for sailing, and both came up with this knife as their best choice, which is why we offer it.
