Great tool

I love it. Well made, durable, stylish. Packaging is beautiful. It's great. That being said, I bought a space pen refill to swap in to it first thing, and the cap was cranked down so tight from the factory that it stripped out the cheap pot metal wrench that they include to do refills, and in the process marred up the beautiful finish on my brand new pen. It is for that reason alone that I deducted a star.

Great.

It's a Space Pen cartridge. It does what it's advertised. Works great.

Great Stocking Stuffer

I purchased the Fat PP Knife (2-pack) as a stocking stuffer for Christmas. It instantly became a hit. The knife itself is not practical for anything other than a boxcutter, but I am sure it would help out in a bind. The knife is very well made very solid! Most of all it sure is fun walking around asking people if they'd like to see my Fat PP.

Excellent Tool

Stabby Labs pen was so good I bought another and love it as my best hand held self defense tool there is in my arsenal.

Awesome Pen Tool

My Daughter surprised me with this for Christmas! It is really some fine engineering in this piece. As advertised, a great piece to have for extra safety protection!

The Massive Nut

Functional tool and fidget spinner all in one

This little guy is a very handy little file setup for breaking edges and works great deburring the ID of cut pipe with the angled facets. And great fun to spin when working at my desk as well. My nut did start to wobble a bit on the bearing and found the inner retainer ring for the bearing had loosened, but was easy to tighten back up with a small pick.

Fun to handle with

The file at each ends are very helpful. Spinning the nut is enjoyable.

A real fun spinner!

Well machined, easily assembled and boy does it spin! I love it! The files are yet to be put to some rigorous testing.

great fidget glad it had spare screws

Great fidget, haven't tested the sanding function yet. But I'm glad it had a spare screw, one of them stripped the threads and would've had a forever loose sander.

Nuts not to have one!

Be nuts not to have a Stabby Nut with an accompanied mini knife on you. Aside from fun, it's a useful tool to measure, to open bottles & whatever needs a quick adjustment.

Loving it!

It's nice and heavy. Solid construction. Spins for a long time. And the files work well. Haven't tried measuring anything with it see how accurate it is yet. I really hope the release more faces. Would love to have diamond files/sharpeners!

Interesting gadget

The Massive Nut was packaged in a nice box. It does require you in install the 'file panels', which I appreciate because I enjoy assembling things. I put the panels on from smoothest to roughest. They were pretty easy to install, but be mindful to not cross thread the hex screws.
When using it as fidget spinner there was some pretty noticeable wobble to the Massive Nut. I saw several people report the same thing. So I took mine apart and weighed each panel. They were all 12 grams, except for two. One was 11 grams and the other was 13 grams. When I put them back on, I placed the panel that weighs 11 grams on the opposite side of the panel that weighs 13 and installed the others. This results in a couple things: 1) The panels are no longer smoothest to roughest. 2) The number markings are out of order. Neither of those things are a deal breaker for me and the wobble is 99% gone.
For a first version/run, I think this is an excellent product. Is there room for improvement, I think so. But I also understand the challenges behind engineering, designing and producing something like this, and wanting it to be as close to 'perfect' as possible. If I lost mine, I would definitely purchase another one. The imperfections don't ruin the product for me, but they might for some people.

Interesting sack

The Nutsack was a surprise, it wasn't what I expected but I think I really like it. It's a high quality leather piece and has a belt loop on it. I will probably not wear it on a belt but it will work in my backpack to hold it in place.

Great little tool

This is a great little tool if you have a need for a compact set of files. It can be kept on a belt with the convenient nutsack! The bearing is silky smooth, however if you’re a snob about spinners and are looking to buy this as a spinner I would pass. The different sides are different coarseness so some have more material removed in the machining than others, resulting in a small bit of vibe. However, if you’re buying this as a tool, it’s great!
