So, I’m fed up of my keys jangling around and making holes in my jeans…

How about a park-style multitool, where your keys folded out like allen keys (obviously you’d need some spacers in-between and car keys would not fit – but this would be great for door keys, bike keys etc)

Ah – just found one:

Tempted to try this now – what should I use to space the keys?

Washers should be fine, it’s all that separates the bits of a multitool anyway.

I’m out.
Mainly because that one has a crank bros logo on it. 😀

Is it possible that any one else could now be working on this idea?

I’ll give you 1p for 100% of the business

like this thing?

Ive had a dragon’s den idea while out on th snowboard last week:

A portable slushy maker in a cup!
A plastic cup. The top has a small crank handle on it linked to a screw below. A folding straw in the lid. Scoop up some fresh (non-yellow) snow, pour in a sachet of flavouring. Crank the handle, and viola! Slushy on the slopes!

I should probably get some one to knock up a 3D model and have it 3D printed in some kind of acrylic.

I like this idea. I hate keys jangling too.
I also like the fact that you can modify a multitool to do the job 😀

big yim – that looks quite good, although would probably certainly cost more getting all my keys re-cut than buying a new multitool and modding it.
Also, wouldn’t fit my Kryptonite key.

I have a larger crank bros tool, so might start with modding that…
Like the idea of always having a 4mm, 5mm and screwdriver on my person too
