regardless, there is simply no way to be sure how someone treats a blade on/off the dock, if it's just you with your $200USD blade you'd like to sell, and want to keep it in saleable condition, then it'd be smart to think twice about lending it out all over the place.
it's a different story if you're a Mfg trying to move units and have a dozen extras to sacrifice as demos
My sister has a used car to sell you. I think it's a 1978 Ford Fairmont. She says it works like a charm, err, 0-60 in 2 seconds. Would you take her word for it?
