Buck 110 Automatic Lockback Folding Pocket Knife BU110BRSA 110BRSA

Engages with the push of a button! Buck’s Folding Hunter was created in 1963 when Al Buck decided that a revolutionary folding lockblade knife was needed by outdoorsmen who wanted a sturdy knife but did not want to carry a long fixed-blade knife. He was right and the result proved to be the key to the company’s future. One of America’s best-selling knives is now available as an automatic! The 110 Auto is easily deployed with the push of a button, readying the 420HC blade quickly and efficiently. Featuring the same classic Macassar Ebony Dymondwood handles and brass bolsters, the 110 Auto will easily become a new collectible for those avid 110 fans. Made in the USA. 

3 3/4" (9.5 cm)
7.1 oz. (201.3 g)
Made In The USA



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..


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.

    Great knife - matches my many-years old Buck 110 - only a little shinier. I love them both.

    Classic Buck 110 with a twist

    Posted by Rich M on 17th Feb 2019

    Every Buck lover should buy this knife. My first 110 was handed down to me from my Grandfather. Deep tradition with Buck. I can't wait to keep this auto version in the family for generations, a true collector piece. Fishbone engraved the bolster with my family initial too.. Quite an awesome experience-thanks for everything guys!

    Buck 110 Auto

    Posted by Glenn Bright on 8th Mar 2018

    I still have the first 110 that my wife bought me in 1983 and believe me it's been through hell and is still functioning and ready to go. The quality of this one is just as good, and I hope to live long enough to get 35 years out of it too. Now I'll have to buy a 2nd one to keep in the box. Functions well with good snap on auto opening, locks in place like a Buck should, and doesn't open in my pocket like cheaper autos that I've tried. Overall another Buck worthy of any collection.

    Awesome auto

    Posted by James on 19th Feb 2018

    What a great knife to get for my first auto. The Buck 110 on its own is fantastic, but turning it into an auto is such a good idea.

    Best Auto Ever!

    Posted by Ed W on 19th Nov 2017

    This is the best automatic knife I've ever owned. It came razor sharp and appears strong enough to last a life time.
