I just received a used Calypso Jr. in VG-10 I bought off Ebay for about 30 bucks. Lucked out, it might as well be brand new. Only complaint I have is that there is a little vertical blade play in the knife. I thought I had read that some have sent there knives back to Spyderco for sharpening and repairs but don't recall for sure. Just wondered if that service really exists and if you need to be the original owner of the knife? Will there be an issue if it is a discontinued model? Any input appreciated.
