The Wild Country Pro Key comes loaded with features. First off, this nut tool has a unique spring leash that keeps you from dropping the tool accidentally, a great feature on longer routes. If you think this is dorky it is easily removed. This nut tool also had one of the biggest areas to bat your hand against, making it the most comfortable nut tool on the market. The Pro Key also boasts one of the better shaped hook designs and cleans nuts and cams very well. In the smallest of cracks we thought its nut cleaning performance was comparable to the Ushba and ever so slightly behind the two Metolius tools.
At $14.95 it is a great value, it has one of the largest areas to pound on with your hand, it comes with a useful (and removable) spring leash, its relatively low profile head cleans most nuts wonderfully and it is second only to the Metolius tools for cleaning extra small micro stoppers. The Pro Key also hangs toward the front of the pack in the cam removal category. It is less than great mainly for climbers who want the lowest possible weight.
