This quite unusual but practical knife block is a relatively fast and simple project for your CNC machine...
There is some manual work involved (edge rounding, glueing and sanding) but with the right tools it won't take too much time...

Step 1: Things You'll Need:

Bill of materials:

(Beech) plywood:
- 700 x 290 x 15mm
- 460 x 340 x 15mm
- 350 x 340 x 15mm
- 260 x 340 x 15mm
Magnet Ø25 x 5mm (NdFeB)
Some 6mm dowels
Wood glue
Clear varnish or walnut oil
3x Felt pads
Your favourite kitchen knifes

Step 2: Overview:

Each main part consists of two respectively three 15mm boards that will later be glued together. It is much simpler to machine it this way than creating solid, thick parts...
Perfect alignment of the boards is ensured by some 6mm dowels...
The 3 main parts are held together by glued mortise / tenon joints. This is rock-solid and very simple to do on a CNC machine but you need to be aware of material thickness tolerances. If your material is considerably thicker or thinner than 15mm you should change the drawings accordingly - otherwise you'll face a lot of manual rework to fit the parts...
The shields knife slots need to be customized to match your blades - you can do this with most 2D CAD programs...
The sharpening steel is just held by a strong magnet inside the soldiers "helmet" - so it unfortunately won't work with ceramic ones...
