Available Features and Options

420HC Steel

This is Buck's standard blade material because it approaches the wear resistance of high carbon alloys while delivering the corrosion resistance of chromium stainless steels. Add our exclusive heat-treat process and you have a very user-friendly combination of superior corrosion resistance with excellent strength for wear resistance and durability. You also have a blade that is easy to resharpen. For best performance we harden to a Rockwell hardness of Rc 58.


The crescent tip makes the blade thinner with a sharper point. This shape provides good control for detail work and cutting in tight places. It is also well suited for intentional punctures like new holes in your belt, etc. While the point of the blade is effective for detail work, it's not as strong as the thicker points on drop points and skinners.


Serrations give your Buck blade greater cutting power. Especially useful when cutting line and/or cables.

Right on

Decided to stop by the Buck factory today after work and man did I luck out! They happened to be having a 50% off sale. Picked this bad boy up along with a bunch of other items! I thought this would be a great camp/ general outdoor knife. Came with a great sheath, is made here in Idaho and I could not be happier. Glad I picked this up. Thanks

Great Piece of kit

I purchased the Buck Sentry 822 recently.What a wonderful piece of kit! It is robust functional and aesthetically pleasing.As if that was not enough the knife only weighs six and a half ounces.The sheath does not disappoint either.Like the knife its made to endure.You guys at Buck take a bow!
