This tool is fundamentally a skew with a round edge, hence the rather acute angle.

The two angles, β1 & β2, can be different, though that is more of a user decision regarding its use. If you choose to go this route, consider making the outer cutting edge (β2) around 30°.

All four surfaces (2 on the red edge; 2 on the blue edge) should be honed to give a smooth, sharp cutting edge.

Sharpness scales (as shown in the grey icon to the left) are used to indicate the recommended sharpness for the blades noted above. You can click on any of the icons showing the sharpness scale and be redirected to the page describing this more. Lower numbers are duller; higher numbers sharper.

These are general recommendations; you will need to use your own judgment, based on the knive’s intended purpose.
