There are three things to consider when you look at the Byrd knives, design, materials choice and fit & finish. Where design is concerned, the same people who bring you Spyderco knives (Sal and Eric) also designed the Byrd class knives. So, design wise the Byrds are excellent.
Where materials are concerned, the steel used is a Chinese made 8Cr13MoV type steel, which is roughly equivalent to AUS8. The steel makes a good utility blade, but you will find that it needs more frequent touch-ups than the VG-10 used in many Spyderco knives. Some have reported a tendency toward rust spotting in some of the earlier Byrd knives, but I haven't heard of any problems lately. All in all, you will find the steel to be up to most tasks that a knife will face. The steel also takes a blisteringly sharp edge.
When you evaluate fit & finish, one must keep in mind the price point of these knives. These knives are not Spyderco brand, they are Byrd knives. That said, in comparison to a Spyderco, I would give them a 8 out of 10. You may run into some sharp edges here and there, but overall, the machining is surprisingly good and when you factor in the price, I would give it a 9.5 out of 10.
As for the Wings itself, the knife is comfortable in hand and smooth in action. It employs radiused tangs and Torx screw construction along with fine textured G10 slabs. The clip may be positioned tip up or down for left or right hand carry.
All in all, the Wings is a great utility knife that should provide years of dependable service.
