BU0840BKS1: 840 Sprint Select Flipper, Black 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.

People who carry a knife every day do so for one very important reason – because they use it everyday. The knives they carry must be as reliable as they are functional, designed to perform effortlessly in whatever lifestyle they are part of.

Buck DNA all the way.
A great no-nonsense flipper with an excellent handle, weight is good, blade sharpness really good. Overall quality well made. It's stonewashed which works fine to hide scratches but I would like a satin finish for $65. Made in USA Buck, good deal.

Pros: Handle Material, Blade Material
Cons: None
Good EDC made in the US
Cons: The flipper action is disappointing. It's a bit sluggish, sometimes failing to open all the way. Not satisfyingly snappy. The fold of the pocket clip is mounted at a pronounced angle, which doesn't match the hem of the pocket, but it's not a big deal. Pros: Great blade, which is the most important thing, right? Mine came paper shaving sharp and is murder on cardboard. Love the shape. I like the handle material and texture. It feels good to me, even though its not premium stuff. I paid about $60 for mine, and I have to say my Civivi Badlands Vagabond is better at $40. But the Buck is American made, so if that's worth anything to you, there you go. In spite of its drawbacks, I like it, and am happy to carry it.
