Hey
I never said that I wouldn't buy a couple! :gimme:

 :D

We will see. Unless the cost can come down I think there will be very few made of these indeed. Anyway, even these days one should be able to make some progress so hopefully I can show a physical version here in a month or two.

So, first physical versions in hardened stainless steel. The one on the bottom is the cross driver - it actually works better than I thought on surface screws. The risk of getting cut on the flat drivers seems less than I imagined. Or I might just haven been lucky.  :D

In the lower middle is the new keychain version. A fair bit bigger than the cross driver but still quite small.

The drivers have longer reach than typical screwdriver bits, and the body itself about the same size as a bit holder. Each driver opens up and locks along the centerline of the tool body. For more torque the drivers on the opposite side can be folded out to the side and used for leverage. Nice rounded corners and quite pocket and keychain friendly.

For keychain use the concept is a little harness that is permanently connected to the keychain, and from which the tool itself can easily be disconnected from. So one doesn't have to mess around with an entire keychain when one wants use it.

(It still needs to get the rivets on. I'm on the fence about polishing it? The locks are clunky without polished surfaces, but then again the slightly rough surface is actually nice to grip.)

It's been a fun one at least.  :)

They have turned out really well Vidar  :like:

It’s still difficult to grasp just how small these are. I know you have them shown next to SAKs and other tools, but maybe a comparison to a matchbox will also help. These tools are really tiny!

My preference is the folding tool.  :tu:

Both of them are sweet. :drool:
I think I prefer the cross driver over the folding one because of budget concerns. :ahhh
But I can see the usefulness of the folding one.

Hooked, like everyone else. ;)

All hail the hook!

Thank you! :tu: I think they would look better polished, but the grip would be worse off. Maybe some middle ground. Either way, these are just for proof of concept and adjusting tolerances so not sure how much I'll put into looks at this point.

I thought about matchboxes, but my matchboxes around here were different sizes. :think: So I figured not a good reference? Either way the folding one is 35 mm long, while the cross one is 19mm. Next time I'll put them next to a ruler..  :facepalm:

They are both silly expensive for what they are!  :D  :ahhh Then again functionality is far from everything.

The folding one is clearly the winner for usefulness. The drivers having reach, torque and being at the centerline do make a difference.

And maybe one can open the opposite driver to 90 degrees for extra torque?

Buy now or regret later

Yes, that is part of the concept.

I put in some temporary rivets to check how it works and the opening closing mechanisms are fine. Yay!  :tu:

Here are some more picture with more scale items, a picture with the tiny flat driver active, and one showing the reach.

Those with big real problems probably don't look on weird screwdrivers anyway. :think:

Thanks!

It is actually kind of cute. Then again I think the same about my excavator so I might be damaged goods.

The mechanisms to keep the drivers folded in when not in use works, and the locks work too. The springs I got for the locks are on the weak side though. I need to get or make some stronger ones for a proper snappy feel.

In the meantime I'll give it some pocket time, and maybe do the keychain harness for it.

Just a suggestion:  make the centre hole a 1/4" hex so it could be used as a bit driver as well (might as well add more functionality)
Thank exactly what I was itching to write

Dream. Wish. Leave nothing undone. Repeat.

It is still way too small for that. :) With a hole for a 1/4" hex in the middle there would be next to no middle left.

In general my design thinking is that if some feature is added it has to work properly. There are too many tools around aiming to do all kinds of stuff and ending up doing very few properly. I'd rather focus on fewer features but have them working well. I do get that for many multitools have a long list of "functions" is a major selling point, but I'd like to focus on actual use and the end user.

Adding features usually add costs as well so that has to be justified too. (This one in particular though is more of a fun project so I've already utterly disregarded all cost considerations and design for assembly practices ::) I even considered making the main body of the larger one in titanium :D).

Like the folding one. I'd go for the rough / stonewashed look. It's perfect to be carried in a keychain. Being polished, it would get scratched in no time and end up looking bad.

 :cheers: :salute:

I have to admit the current look, being fairly close to stonewashed, is growing on me. I've been carrying it in pockets for a while now, but it really needs a keychain just to keep track of it. I'm thinking of maybe doing the keychain connector to match the pins. Maybe some bronze. Or alternatively a stainless steel similar to the main color.

It might do fine polished as well as it hardened steel throughout. Softer things like keys, coin and such should not be a problem with regards to skratching. That said the hardness of this one is softer than it ought to be for a long life of screwdriving, so that needs improving if I'm ever to make more of these.

Functionality is actually good. It works pretty much as a stubby screw driver, so it is easy to keep pressure down while turning. I got lucky there!  :D
