Knowing that you have a lazy, kleptomaniac in the house, wear an apron and get in the habit of dropping your scissors in you pocket instead of leaving them in plain view. Also, does he have a "favorite" tool that you can find to use, so that it no longer works? Men's tools are expensive, too, and he might get the message. Hmmmm. Shaving the dog or the fuzz off something might get the point across. Good luck. I keep my scissors out of sight and keep a pair of utility scissors in every room. He needs to learn manners! ( My husband lost my favorite bread knife which, too, is not replaceable, two phones, and several other items when he placed them on the back bumper of our truck when he was working in the yard. After a tantrum or two by me, he has learned to put them anywhere but on the truck bumper!
