The Wings is the only Spyderco/byrd I've had to send in under warranty, because my first example had a warped handle. The replacement's better, but it's still lacking on F&F. Shame, because the Wings Slipit is high quality for the price and I was expecting the same. I also keep comparing it to the C-44 Dyad, which comes in a much less bulky package, so the Wings doesn't get much pocket time from me.
in hand: Pingo, HAP-40 Stretch.
