BU0840BLS: 840 Sprint Select Flipper, Blue GRN Handle

Buck Knives

Utilizing ball bearing technology, the Buck Sprint Select is designed for smooth and efficient opening with a reduction in friction for rapid blade deployment. A sturdy liner lock secures the blade while in use while the sturdy GRN handles give a secure grip. Available in multiple colors, each Select model utilizes 420HC steel. This knife features a convenient deep carry pocket clip for easy carry.

Drop Point

This blade is full bellied with a strong, thick point for heavier tasks. It can also be used as a general work knife. The top of the blade drops down toward the tip, which minimizes accidental puncturing while skinning. The drop point blade is strong and very versatile.

One-Handed Opening

Has a thumb stud, blade hole or other feature to facilitate one-hand use. Some models are one-hand opening and one-hand closing as well.

The steel behind the blades

Buck is a market leader in edge retention thanks to their steel selections and heat treat process pioneered by Paul Bos, whose heat-treating system has proven to the best in the business. Each blade is put through a rigorous heat treat process and quality performance test then is tempered to the appropriate Rockwell Hardness through a heating, freezing and reheating system. This process, along with attention to detail through grinding and hand edging, is the foundation of Buck’s Edge2X technology. This gives you longer edge life, ease of resharpening and a blade that will not fail you.

420HC

420HC is Buck’s standard steel with great edge retention and corrosion resistance. This industry standard is easily resharpened. For best performance, Buck hardens to a standard Rc 58-60.

Good work knife
Got this to replace a D2 blade knife that requires more attention to keep it in top shape. Nice size, blade thickness and grind for my use as a facilities tech. Minor edge maintenance is all I have needed so far. Blade doesn't flex like some other edc offerings I have tried. SS is less maintenance overall. Made in USA is a plus.

Great except for one thing...
I like everything about this knife except the pocket clip, which pokes me in the palm and makes a bad hot spot. Not a big deal if you're just using the knife for an occasional quick cut, but I wouldn't take this knife camping or into any context where I might need to use it for an extended period--the pocket clip would eventually raise a blister for sure. The action is great and the blade is just what I'd expect from an American-made Buck. The texture and shape of the handles is excellent and would be very economical if not ruined by the pocket clip.
