DMM - Nutbuster
It may seem strange, considering its essential simplicity, but DMM is quite proud of the Nutbuster because it embodies their core values - it is very well made and works very, very well. The Nutbuster blade is laser cut in Sheffield from the finest stainless steel and then given a taper so that it can access narrow placements, but is still stiff enough to dislodge nuts that are welded in - simply compare the blade to anything else on the market and you will see the difference. The round hole in front of the rubber handle both reduces weight and helps accuracy so that you get nuts out faster without damaging their wires. The rubber handle makes the Nutbuster very easy to handle and allows wires to be hit hard without the blade digging into your hand. The rubber handle can be removed if you want to really hit the blade hard with a stone. The Nutbuster can be slung directly on a carabiner, but mountain rescue teams get fed up of digging nut keys out of bodies so it is always best to sling any nut key on a short piece of climbing cord. The danger of impalement in a fall is is also why DMM did not incorporate a gate into the Nutbuster - plus the mini, integral gates are a pain to use with cold fingers or with gloves.
