The nicest nut tool out there.
The Pro-Key is a superb nut key with a host of great features to help recover stuck gear.
The Pro-key comes with a new precision ground tip which allows access to the smallest slots, as well as a wire gate at the top which allows a direct clip to the harness. Added to this, a one piece 'folded top' gives a bigger surface area to allow a strong push with the palm. Large holes keep the weight down.
