I had a thought about the $10 advance thing. Lets say the hone goes missing and only a dozen have tried it. Perhaps it was lost in transit (uninsured), someone broke it accidentally or worst case scenario someone stole it. I wouldn't feel comfortable keeping the money of the ones that never got to try it, whether they agreed to the terms or not.
I guess thats why I thought the deposit idea was better, the last person who had it would be responsible.
Apart from that, is there no one thats interested in this idea? All that have commented so far have a Japanese hone.
