Arcos knife sharpening spatula with 2-sided diamond file

The easiest and most efficient manual knife sharpener. It is easier to maintain the sharpening angle with a spatula-shaped sharpener than with a stick, so the chance of error is reduced. With a diamond file, you can sharpen everything that requires sharpening, from a high-end Japanese kitchen knife to a scythe. The diamond file also does not require oil or water, like similar sharpening stones.
