SPBY05P: BY05P byrd Flight
byrd Knife Designed by Spyderco
The Flight has a hollow-ground blade manufactured using 8Cr13MoV stainless steel, which is similar to AUS-8 in its properties, performance and function. 8Cr13MoV steel contains both molybdenum and vanadium. Molybdenum enhances the strength and hardness of the steel, vanadium its wear resistance and toughness. Carbon augments the steel's tensile strength and increases its resistance to wear and abrasion. Resulting from this recipe is blade steel that retains a sharp cutting edge over time and use. Most byrds are available with a plain or combination plain/serrated cutting edge.

The "comet" shaped opening hole is a trademark of the byrd line and is synonymous with the stringent quality requirements, high performance materials and manufacturing, which go into every knife. fully stainless handles have a sequence of ergonomic curves that fit into the palm for comfort and fatigue-free control while cutting. For additional safety, a portion of the lock release is ground away. This is a design add-on conceived by custom knifemaker David Boye and eliminates the chance of gripping the knife tightly enough to unintentionally release the lock. All byrds feature a pocket clip that clips the knife inside a pocket and it attaches to either end of the folder for tip-up or tip-down right-hand carry.

The original locking mechanism. It can be found mid spine or at the bottom of the handle, and it provides tight lockup that will wear well.

One Step Forward, Two Steps Back
The standard Lock-Back hasn't lost any ground since it was first introduced decades ago, and if not for Spyderco (they call it a Back-Lock) these knives would probably still have thumbnail slits and require both hands for opening and closing the blade. And it should be little wonder why Spyderco provides such a variety of back-locks -- the reliability of the design is etched in stone. Enter the Byrd series of Spyderco knives and we find that most of these folders are back-locks, and all except one I have purchased were acceptable in their appearances considering the inherent rusticity of the series. They are every bit usable, and under certain conditions can be the better choice. Upon receiving this Byrd Flight it immediately took the place of my Cara Cara2 since both knives are back-locks and are very similar in size and design. The reason is because after reading how Spyderco has implemented a better build process in this latest 2nd generation of Byrds, instead of better, what I'm observing are blades that appear rough and wavy as if they were somehow passed over and sent out prior to being completed. The blade of the now almost extinct Flight is superior, as are all the blades of the Byrds I have that were hollow-ground sharpened.

Cons: None
Spyderco Byrd Flight is a great knife!
This is a great knife for the price. Nearly the quality of a Spyderco. Very solid feel, tight blade, extremely sharp. I accidentally cut myself while polishing the blade, so be careful! I changed the clip position so that it is tip up. For me it is more natural to open that way. Might order the G10 version next.

I order you to buy this knife!!
I was beginning to think I would never find a decent repalecement for my Sogwinder I, until this little beauty showed up. All steel construction, excellent lock up, full backspacer and fit and finish that is every bit as good as the Japanese made Spyderco knives (I DO have a Dragonfly) make this knife a real winner. Also like the fact that both pivots are completely tiny torx head bolts to work loose. for $20 this knife is outstanding. I'd give it six stars if I could. I don't understand all the love for "lightweight" knives. It just tells me the dang thing is made of plastic and aluminum. Sick! I say, the heavier the better. If it's too heavy, then get stronger. Only one material should ever be used to build knives: Steel, and lots of it!
