SIEGER LONG LIFE. 20 CM RUBY

This knife sharpener made from synthetic ruby is 20 times harder than hardened steel (20.000 Knoop, approx. 200 HRC). Unusual is the high effectivity (less time exposure) in combination with an extraordinary fine result. Additional this sharpener is more persistent than a diamond sharpener because this is a full material not only a coating. The knife sharpener can be used wet or dry. Please clean with a sponge after use.
