Great tool

  • Familiarity: I've put it through the wringer

Great for getting stuck nuts out. Perfect for cracking open a beer.


    Bought it for my daughter, sturdy and gets the job done.

    It does the job

    • Familiarity: I've used it several times

    It's hard to give this a bad rating because it does exactly what it's intended for and does a good job. With that said, I find the tools with a built in carabiner more practical and efficient. If this tool had a built in biner it would bring the rating from a 2 star to a 5 star.

    Nothing Fancy

    • Familiarity: I've put it through the wringer

    And that's really it. Nothing too fancy but it gets the job done and works fine for it purpose as a nut tool.

    The edges on the metal are a little sharp but other than that I have no real complaints. Oh, and it definitely works great as a bottle opener.

    Pass on this

      This is a dated and uncomfortable design. Sure you can rap on it with a Binet to loosen a stuck piece but why not spend $5 more on a DMM, wild country or other nut tool that has had some actual care put into the design and manufacture. Cleaning is often awkward and taxing, spend a couple more bucks on something that simply works better.

      Useful on the wall and off the wall

      It's a good solid tool, plus you use it to crack open a beer.

      Dont drop it

      • Familiarity: I've used it several times

      Nut tool is great. Wish it came with sort of strap to keep it to your harness. Sure you could get creative with it.

      Haven't used it for climbing yet,

      • Familiarity: I've used it several times

      But the bottle opener works great!

      Climb On

        You have to carry one....why not stay with a name you trust. Black Diamond gets it done again.

        Removes nuts

          Don't know what I can say about a nut tool. It works great, lightweight, sturdy and all that.


          • Familiarity: I've put it through the wringer

          Great nut too, does the job! Does tend to be a bit sharp and jagged so pulling on it all day gets a little rough on the hands, also wish it had some sort of leash on it.

          Basic tool

          • Familiarity: I've used it once or twice and have initial impressions

          This is a very basic, simple nut tool. It appears to be stamped chromoly steel. It is light weight, but this is somewhat deceiving. Most of the time I end up attaching it to my harness with a carabiner, so you really have to include the weight of a carabiner when you are comparing this tool to other ones that have an attachment method built in. I bought this on sale as a loaner if my climbing partner/follower doesn’t have one. The price is right for such a plain tool and it is one of the least expensive nut picks available. However, similar to how the weight is deceiving, you have to include the cost of a 'biner when considering the price. Like any nut tool, it is worth its’ weight in gold when it helps you free stuck pro.

          Decent - kind of jagged

          • Familiarity: I've put it through the wringer

          Pretty good nut tool - can definitely dislodge a piece. Pretty rough around the edges though and doesn't seem very well machined. I definitely worry about slicing something in my pack with a rope, sleeping pad, thin puffy, etc...

          You get what you pay for.

          • Familiarity: I've put it through the wringer

          It's simple, lightweight, and gets the job done.

          Like some people have said, it'd be nice if it had a bungee, a better grip, but for $10, I think it's what can be expected.

          It does the job

            I can't compare this nut tool to any others, but it does the job. I've never had any problems with it and can recommend it for sure.


            • Familiarity: I've put it through the wringer

            This is a great nut tool! works well for really getting stuck nuts and hexes out. I just used this nut tool and a rock to beat a stuck cam lower into a crack where it widened out and we could get it out.

            This nut tool is good if you and your partner use a lot of nuts and hexes, or if you are aid climbing and the nuts need a good solid tap from the bottom to get out.

            The draw backs to this tool are that you need a separate biner to hang it from, its kind of long, and it clangs around and makes a bit of noise that can get annoying after a while.

            Solid and Light, No Clip

            • Familiarity: I've used it several times

            This nut tool works very well and is light enough to barely be noticed. My one gripe is the lack of Caribiner clip built in to the handle. This forced me to larksfoot some cordalette to the end, or to directly attach a caribiner. Both of these options added excessive bulk to the tool. I would recommend finding a tool with a caribiner clip.

            Don't get caught without it!

            • Familiarity: I've put it through the wringer

            Unless you enjoy decorating the wall with your gear, include this as an essential item on your rack. Even if your not the one cleaning that nut you jammed into the crack a bit too hard, your partner will definitely thank you. At the very least you wont need to buy a new set of nuts every season.

            Still in one piece, no rust. Perfect.

            Basic... that's all you need!

            • Familiarity: I've put it through the wringer

            This is the only nut tool I've ever owned, and is likely the only one I will ever own in the future. It is simple, lightweight, and it works. It sure is noisy while it klanks around on a carabiner. This is an essential piece of gear for all you new climbers out there, following routes day after day.
