LittleHammer delivers a percussive force to release stuck nuts, hexes, and RP’s easily with one hand / either hand.
Stuck nuts = bruised palms, bloody knuckles, and stalled climbing.

As simple as that.
We’ve had a lot of valuable feedback on LittleHammer, here’s the best written response to it by a very experienced climber: LittleHammer feedback
Whether you’re using your dominant hand or not, LittleHammer will work flawlessly. You’ll never get pumped trying to hack a nut out; nor need two hands to remove a nut again.
LittleHammer excels when dealing with RP’s and other micro nuts that are hard to dislodge being too small to strike accurately.
Of course, LittleHammer can be used for all the usual nut tool tasks like levering and hooking cam triggers too.
Not just nuts can be saved.
The hook on the handle end of LittleHammer is for reverse impacts to get aid gear out: beaks, tomahawks, and peckers. No other nut tool can perform this function. We’ve also had good results experimenting with stuck cams using the reverse impact on each cam lobe. More from another climber on this function at the bottom of this feedback post.
Highest quality materials and craftsmanship.
LittleHammer is the heavyweight of nut tools at 130g (4 1/2oz). It is laser-cut from 2.6mm (7/64″) stainless steel with a brass impact weight and galvanised spring so it will last in all weather. Designed for years of hard use in trad or aid climbing; simple Allen screw assembly means it can be disassembled easily to be maintained for a long life of service.
From our successful Kickstarter campaign to fund the first production batch, LittleHammer will be manufactured in Australia; Central Victoria; close to home. This is an area that has a long history of engineering and innovation dating back to the gold rush.
We prefer to manufacture locally to support our community, contribute to our local economy, and help retain these great engineering skills.

Trigger tuning — LittleHammer 1.0
(LittleHammer 1.1’s improved design won’t need tuning for a long time, I had made the trigger tolerances too fine in the initial production run so had to hand file each one of the 200!)
LittleHammer is designed to be maintained: simple screw access to the working parts means you can tune it up to your desired performance. Each unit is checked and tuned before it’s sent out, but over time even the hard stainless steel will wear, effecting the fine tolerances of the trigger. Here’s how to do it:
The screws holding the brass impact weight together need a 2mm Allen key. They will be a bit stiff as there is Loctite on the thread. Keep a note of the stainless steel spacer’s orientation so it can go back the same way, even put a mark on it.
If the trigger is too hard to release, file the top front corner of the spacer and/or the lower corner of the trigger notch, just a little filing should help.
If the trigger won’t catch or is too easy to release, file the front end of the spacer to square it up, particularly the top edge that engages with the trigger notch. Don’t make it too sharp a corner as this will make it hard to release.
You can also file the pivot point. If you follow the long side of the trigger notch back to where it meets the main track, there is a slight angled corner there (about 178º). Filing this corner allows the spacer to sit up higher in the trigger notch.
If you don’t have Loctite to re-assemble don’t worry, I didn’t use it on the prototypes and they only required the occasional tighten up.
The spring on LittleHammer 1.0 has one ground (flat) end, this goes against the impact weight. The flat end is to stop the spring catching under the impact weight, this stops it engaging with the trigger notch, check the spring is clear before you work on the trigger.
If you are having problems with your trigger and don’t have the tools, post it back to Climb Design and we’ll tune it up and return it to you ASAP. Contact us to arrange a tune-up.
