I stumbled upon a BJÖRN knife (Eitri Affilatura) some time ago. Why not give it a try? Anything that helps to remove effectively mature schnauzer hair without cutting is welcome. BJÖRN is a handy tool, but it has to be used precisely, on every square centimeter and with the same power. Stripping with BJÖRN is more time-consuming than stripping with a classic stripping knife, but it pays off. Of course, if we want to achieve top-quality hair.
