So ever since I can remember I have haaaated carrying keys. They're uncomfortable sitting in your pockets all day, they make it hard to find change when you need it, they scratch up everything around them, be it cell phones, cameras, etc.. and when you really think about it, your standard keychain is really just a terrible design. Why would you subject yourself to that? Well I've decided enough is enough and set out to make what I think is a much more friendly and functional keychain. My criteria for this new design are as follows:
- Compact and foldable
- Comfortable in the pocket
- Easy to distinguish from all other possible pocket contents
- Not rough or abrasive
- Aesthetically pleasing
- No jingling!
Step 1: Crank Brothers M5 Multitool...
I found this great little Crank Brothers M5 Tool
that was the perfect start. It is designed for cyclists and as such is very lightweight. Not only would it be the perfect housing for my keys, but it also sported a variety of allen wrenches and a philips head screwdriver as well. Sweet! If that wasn't motivation enough, it was cheap at only 12 bucks!
Step 2: Take it all apart...
The first real step was to take the M5 apart and see what kind of tolerances I would be working with and how everything was going to fit together. I ended up adding a couple flat washers to make up for the space differences between the allen wrenches I removed and the keys I added.
I was pleased to find that your standard house and car keys are the perfect length to fit snugly inside the folded M5, so you don't have to worry about adjusting the position of the keyholes. The only part of my keys that really required any modification at all were the little square holes. I imagine there are key blanks out there that have a large enough hole to work right out of the box with no modification at all, but alas, I would had to make my square keys fit a round peg.
