Fiskars Edge Roll-Sharp Blade sharpener
Blade sharpener in two different thicknesses, two accessories in one, both for large knives and small ones.
It does not require electricity. Also fit for left-handers. Use at least once a month, since a blade regularly sharpened with Fiskars Roll-Sharp preserves its cutting edge and knives have a longer duration.
The second position allows to sharpen thicker blades.
