A manual rolling knife sharpener with two sharpening stages, a diamond-coated roller for fast edge restoration and a ceramic disc for fine honing.
A magnetic angle guide clips onto the blade and locks it at a fixed angle every pass, 15 degrees for fine edges or 20 degrees for sturdier ones. The rolling mechanism draws the blade across the surface in even, controlled passes, so there is no rocking, guessing, or freehand angle holding.
