Letter knife

A simple knife, fully printable, that turned out pretty good. The edges are quite sharp and works for example for opening letters.
For the "metal" parts I used a [filament with steel powder](https://www.3djake.se/colorfabb/steelfill) and for the "wood" parts I used one with wood fibers in it.
After printing I used sand paper on the blade to make it smooth.

The knife consists of below parts. It is easily assembled by just pushing the parts together, no gluing needed.
* 1 x blade
* 1 x guard
* 2 x handles
* 2-3 x rivets
