The nut tool is does the job well. However, The black finish does not match (nit picking) with the rest of the chrome finished gear black diamond offers. The bottle opener is a neat idea. The nut tool would be more beneficial if there was a way to connect the tool to a gear sling. I had to purchase a small piece of webbing and another biner in order to secrue it to my second. Other than the finish, the harsh edges, and the lack of a lanyard, it is a solid piece of gear.
Well, BD's nut tool 'does the job', but not much else. Finish isn't exactly brilliant, and the clever ideas that all competitors have included in their versions of the nut tool are here absent. E.g. Hex to tighten the standard 17mm bolts, clip included, bigger overmoulded handle to grip better, etc.
Overall, BD's nut tool does the job, but doesn't stand out above the rest
I love BD products, and usually super happy with them. However, I'm always lusting over friends nut tools.
My biggest complaint is that many other tools come with a built-in way to connect this to a harness. One of my friends has a nut tool with an extendable leash (it is coiled like a telephone cord, which makes it easy to access the tool from the harness), and others have tools with a built-in clip or carabiner.
As another user commented, the design also has sharper edges which are a little rough on the hands. The BD nut tool works, but its pretty bare bones and unexciting as far as gear goes.
Unfortunately I have another nut tool that I prefer (Ti ¨Ushba¨ from Russia). I think all nut tools should have a small flat section on the non-hook end (like my Ushba and some other brands) so you don´t have to hack up your hand (or Krabs when your desperate). Fine if you have a rock or aid hammer though . Stamped out of sheet and unmachined, so the edges are sharp. Good shape on the hook, nice weight saving relief. I keep mine as a backup, and a cool bottle opener, for after a long days climbing.
