For many years I used to keep my sawzall at a buddies house. Because my Wife decided-- not once-- but twice to cut down the couch we had at the time with the sawzall. The first time she wanted a "small sectional" in her words. The second time she just wanted 2 smaller couches. At the time we were dirt poor and we couldn't afford to be replacing a couch just 'because'.
I eventually had to enforce a 'no touch my tools' rule and you don't fix ANYTHING rule to save my sanity and life.
