Communication is the key to a healthy relationship. While I agree not to sweat the small stuff, I would communicate to my wife that if she used one of my LN chisels to do the job of a free HF screw driver there would be consequences.
Then again that is not a conversation we have ever needed to have,she is a pretty smart Lady and is educated enough on the subject of tools so know the right tool for the job... she says she learns through osmosis by ignoring me talk through projects.
The running joke is she can rebuild a carburetor despite never having touched one.
