I really like using them to clean fish ...call me a wuss .But my Dad had a Canada trip canceled when a guy cleaned a walleye then stabbed himself with the fillet knife and didn't wash it good ..When he woke up the next day his was swollen twice the size ...they managed to get him to a hospital and it was serious they kept him for 2 days .It could have been worse .Fish slime it toxic to the bloodstream
