About a year ago I purchased a Case "Rancher Stag" CV medium stockman. It stayed on my display board for the past year until I decided I wanted to start EDCing it. It is a great knife, however, I noticed that the backspring on the spey blade is sort of loose. It still has some tension, but the blade does not snap into the open position at all. When it's open, you can push on the blade and it will begin to close. The best way to describe it is it feels like an an Opinel. Is this something I should contact them about? Since I do plan on using the knife I'd like to have it fixed/replaced. I've never had a bad Case knife so I don't really know how their warranty works. And does it matter that the knife was purchased probaby around a year ago and I don't have a receipt or anything?
