I bought the Paring knife and the 5 inch utility knife about 8 months ago. 1 sheet of Scotchbrite wiped out the paring knife, (I bought to see how it would hold up on that stuff since I use it at work, Razor blade will do 3 sheets then it's toast ) I've been using the utility knife for reasonable cutting chores and it still slices a tomato. (I just sliced up some stew beef the other day )
