it certainly does what a nut tool needs to do - it gets gear unstuck. but, then again, what nut tool doesn't do that? these tools differ from one another only in terms of the 'bells and whistles' - palm protector, little wiregate, keeper leash. this palm protector works, but the wiregates on the metolius freenut tools i've used or fooled around with don't snap closed like carabiner gates normally do, making it sort of pointless. if you're looking for a good nut tool with worthwhile extras, go for the Wild Country Pro-Key nut tool. the palm protector is more integrated to the device, the gate actually snaps closed, and it comes with a thin, coiled-wire leash and minibiner that doesn't interfere when you're bashing out a piece. as an added bonus, the integrated leash saves you a carabiner and sling to attach your nut tool to yourself.
