Sharpen with a guide instead of guessing the angle
Freehand sharpening can feel inconsistent: the angle changes, pressure varies and the result depends heavily on technique.
The NOVNEST magnetic guide supports the blade at a fixed 15° or 20° angle while the rolling discs bring the sharpening motion to the edge.
Use light, even pressure from heel to tip
Flip the knife to repeat on the other side
Finish with the ceramic disc for a smoother edge
