I have two interests in this thread: Pipe tools and cats.
Cats do love to spirit away small shiny objects. One of my rescue Maine Coon type cats out of a drainpipe took the key from our buffet, but he was so generous as to leave it in one of my shoes! So check your shoes. I'm told that this sort of gift giving by cats (and dogs and crows) is a gesture of high esteem.
I have a number of pipe tools from the Czechs, Brebbia, Dr. Grabow, Savinelli, and so on. It's just one of those ironic principles in life that though you may lose your expensive treasured pipe tools, your pipe nails will follow you home in a cab if they have to. You simply can't lose a $1.29 pipe nail, not possible.
