Here's a twist on your story. Years ago when we moved into our new house, I used my husband's Gerber knife
to cut shelf paper. It was a smaller knife, worked better than scissors (to get a good cut) and was very sharp.
When my husband got home and saw what I was doing, he didn't say a word but took the knife from me, looked at it then pointed to the small chipped place on the blade. I was so sorry and bless his heart he didn't yell or anything, he just put it away. I felt terrible. I found out when I contacted the company that the knife could be re-sharpened. I sent it off and it was made good as new. Maybe you can tell him this story and he'll get the hint.
