That's too bad.
However, you might do better reselling the Drunken on the 2ndary market than returning it, since the initial run is already sold out at Spyderco and dealers still aren't showing it in stock either. No reason IMO why you shouldn't take economic advantage of a short term supply/demand situation to make a few $'s if you didn't buy it solely for the purpose of flipping it for profit.
There are a couple offered for sale right now on EB for $450 and one at auction that is currently bid at $350 w/2 days left to go; will be interesting to see what that one finally sells for. However, only 1 has actually sold so far for $400; $10 below MSRP.
In any event, I'm keeping mine despite the clip issue because it was always going to be a "safe queen" for me, since I don't make it a practice to carry or use $400 knives. However, I will be on the lookout for a better clip for it down the road.
