Works very well and extremely portable put an excellent edge in my pocket knives and multi tool blades in a few minutes i achieved excellent results on all blade types shown

Carbon steel blades were easier to sharpen to an ‘arm hair shaving’ sharpness while stainless steel took a little more time but managed to get them sharp enough to cleanly slice paper without ripping it

I advise you to watch demo videos on “you tube” before using this sharpener to make sure you are using it correctly

Adopting the correct angle 30 degrees with the right amount of pressure very light and applying water to the stone all result in extremely sharp blades with no burrs dull spots or chips
