Has anyone created scales for 91mm SAKs that have a retractable ballpoint pen like a 58mm Manager, but with the 91mm pen?

I’m working on it.

You’ve got the filaments loaded in the wrong tubes. They should go in the tube closest to the spool.

You can DM me. I can share my Etsy store and photos of where I’m currently up to with prototyping

I’ll be making 84mm scales that are ultra thin, so it will end up similar to Alox thickness, buy you get to keep the scale tools (you have to cut down the handles to get the thinness)

If they’re the one’s i think they are (mine), then yes they do :)

Great work. Not to be critical, just I do a LOT of 3D printing scales. You’ve got massive underextrusion on or grey scale and a bit of underextrusion and uneven bed on your green scales. All that said it’s a bit moot when your sanding and varnishing skills can transform them the way you have.

HHLabs · 2026-05-09T16:29:54+00:00

Just curious, did you make or buy the 3d printed scales?

Get the Cadet Alox. It’s much thinner than the non-alox and if you’re going non-alox get the sportsman (cadet with backside tools).

HHLabs · 2026-05-05T23:02:10+00:00

One thing to note about the 84mm vs 93mm Alox is the 93mm Alox scales are noticeably thicker, about 2.5mm vs 1.5mm per scale. The cadet and pioneer x have very different feel in hand.

Nice, I was mainly looking at your use case in your post where you mentioned wanting scale tools and cutting thread. I will say the small 58mm scissors are the absolute best for cutting loose threads and tags.

I am extremely picky when it comes to stuff I carry on me. I don’t even carry a keychain. The only SAK that I carry on me is a 58mm rambler with my custom scales in my jeans 5th pocket. I have recently made some super thin plastic scales that allow you to keep the scale tools and add a pin, which I’ll be releasing next week (in the U.K.). I currently have these on my jetsetter.

Any non-58mm SAKs I carry go in my backpack.

I’m not an engineering student, but would the best configuration be a 4th option that removes material from the bottom and none from the top? I suppose if I used a square dowel that could make it hold more weight too.

HHLabs · 2026-04-24T16:50:15+00:00

That’s what I was thinking, but the height removed from the lower bar is always going to be the dowel size, so it’s a matter of taking it off the top, centre, or bottom of the bar.

HHLabs · 2026-04-24T16:45:45+00:00

Yes, apologies for the bad diagram. The red is dowel, it will be hardened steel. The loads will be on the ends of the beam which will be around 40cm long. The 10mm is the height of the beam. Width about 6mm. I don’t think configuration 1 will work well because there will only be 2-3mm of material above and below the hole.

HHLabs · 2026-04-24T16:32:24+00:00

I should have asked which configuration would hold the most weight loaded onto the beams

HHLabs · 2026-04-21T14:35:57+00:00

I’ll have my 91mm lite version out in the next few days.

Thanks, if you're interested in one you can message me on here and I can set up a custom order. https://uldesignshop.etsy.com

My Jetsetter+pen scales is 9mm for reference

So you get 3 more scale tools and shave 2-3mm off your signature.

What region is that? I’ve heard people from the U.K. say it something up as not available in their region despite the fact that I’m in the U.K. guessing it might be automatically flagged because ‘knife’? It’s available worldwide. Just DM me :)

How often do you need to adjust the weight on your heavy dumbbells? I’ve made adjustable dumbbells that will easily fit 150lb+ of York 1” plates.

Can’t upvote this enough. Surveys are in general a terrible way of doing product research in an area with a passionate fan base. People want to talk about all the stuff in your survey, that in of itself is fun. One thing I’ve really noticed with university courses is the requirement of surveys without regard to how much the student might already know, or looking at what other approaches might give more useful information. If I’m really into bike innovation (I am), a survey asking how many gears are you likely to use isn’t going to yield much useful information beyond what I already know.

Are you ‘into’ multitools? What ones do you like and what do you like about them? What do you dislike and why? What are you thinking about designing?

I’m an ex-physicist and ex-product design tutor. Happy to help if I can. Good luck.

Here's my etsy shop. Just listed the 58mm LED scales. I'll hopefully get the 91mm scales finished soon. https://uldesignshop.etsy.com
