Sold your piano?

Did people once keep shaving razors inside pianos? I'm looking for background to a reference or joke an older man made to me. Specifically, he asked if I had sold my piano, inside which I would keep my razor, as an explanation for why I hadn't shaved my face that day. It was said in jest, and I don't think that he's simply crazy.

It has me baffled anyway.

I can't think of any reason why anyone would keep their razor in a piano - and good reasons why they wouldn't: it would be an extremely odd thing to do.

Unless I am missing something...

DFG

I am seeing a piano player in a bar or house of ill repute who keeps a straight razor in his piano in case of trouble. Just a guess.
