Available Features and Options

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.

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.
