Works well so far. The carbide is thick and feels good. Some packages contain the word "fish" instead of "fish" (e.g. This countersink). The website for Affinity Tools (US distributor of Fisch Tools) indicates that both tools are from the same manufacturer. This is also confirmed by the manufacturer's answer of 04/05/18. See application below: > Thank you for purchasing FISH. > So please don't worry, this is Austrian quality and we sell FISCH and FISCH. Note: the answer didn't explain the difference, if any. All my fishing tackle comes from Austria.
