I've been a fan of Al Mar knives for the past thirty five years, Al Mar died a few years ago and he is missed by many in the knife community.
His knives weren't expensive but the quality of the steal is brilliant. The stinger must be the smallest of his knife range, a great little knife for a keyring, the knife arrived razor sharp, and I for one can guarantee it will remain like that after constant rugged use....so be very careful how you handle this little monster.
