Knife Sharpener guide 17 degrees

This is a kitchen knife sharpener guide designed in 17 degrees angle inclination - which others say the best angle for sharpening a knife. I could have designed this simpler, but since I have some spare bearings from my MTB and some screws and nuts I took time to integrate them.. the result was very good and I made my wife's ordinary kitchen knives razor sharp.

Integrated parts:

4 pcs. of 15267-2RS Ball bearing (15 x 26 x 7 mm)
4 pcs. of M4 nut
4 pcs. of M4 x 10 screw


Compatible with:

- Sharpening stone 1000/4000 Grit (Dimension: 18 x 6 x 3 cm)
- Rubber base holder
