Today, I get a USPS Priority package in the mail from Lee Valley which is odd because I haven't ordered anything from them recently. Inside is a note explaining that several owners of the same sharpener requested some sort of cover for it. Consequently, Lee Valley put together a cover of nylon and sent me one. Even though I bought the thing ages ago. There aren't many companies that have this level of service.
As long as I'm buying stuff they sell, Lee Valley will be the first place I look! Thanks Rob!
