Pocketknife inspired keychain

Here is my first thing.

I've always wanted a pocketknife inspired key holder, but most i found were a bit bulky or big.

The design is uploaded with both "sharp" edges, and with fillet.

I tried to make a minimalistic approach with just a two part design and nothing more. Use a M5 nut and bolt and you'r all set.

If you are adding several keys to the chain, i suggest that you use washers.
