I think the simple truth is when you loan or give a razor or any other thing to someone else (ever loan tools to someone?) you have to accept the fact you may never see it again or if you do it may come back in a very different condition. If you are concerned about this you shouldn't give things to others. Hopefully others take care of things however I've had enough situations where I've lent things to friends and relatives who I know well and the outcome wasn't good. Giving to a stranger or acquaintance can be more dicey.
That's how I look at it.
