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 as the non automatic 110 you love, the 110 Auto will easily become a new collectible. Made in the USA.

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.

Best knives ever

I have always carried a Buck 110 since I was a teen, with the law change in Texas I thought an automatic knife would be great! Imagine my suprise when I found my favorite knife with a new twist, and not a modified version but factory made, couldn't ask for anything better!

Awesome Knife

The Buck 110 Auto Folder is a great knife for the out doors, it can handle some tough jobs, whether on the farm or out camping. It could have a better sheath. My sis got this one for me for my birthday and I really like the knife.

Buck 110 auto

I love this knife. Ever since I was a teenager I've had the Buck 110, and now it's in an automatic. Thank you!

Finally got my blade

It took a very long time and a lot of perseverance to be able to get my switchblade. I have a lot of buck knives, but the 110 has never failed me kayak fishing and cutting heads off big redfish, catfish, sharks, etc. When I saw a 110 auto I couldn't sleep yet nobody carried it locally. I kept calling corporate Buck HQ until hey gave me the number of a local supplier who could get it for me. I'm a happy man! Sharpest blade I've ever seen. Time for offshore kayak fishing now!!!

It's the most beautiful knife that I have!

I have my wife to thank for summing-up the attributes of this lovely, smooth-opening, well-built knife: " It's the most beautiful knife that you have!" She said it all.

Great knife

I've always loved Buck 110s & 112s and wondered why they didn't make an automatic. Just received mine today and absolutely love it. Classic Buck quality and push button opening. Now, if they'd only make it in the 112, too.

Awesome Knife

Bought the `110 Auto recently and love the knife. Attention to detail and overall quality is better than some knives I paid twice as much for. This one is a keeper.

Love the knife

Buck clearly looked at some conversions before designing this one. The wood isn't hollow immediately behind the button like round button conversions, the tab that engages the blade inside the handle is steel instead of brass like the conversions, and the wood is riveted to the handle ahead of the button-no worries about it pulling away from the liner like all three conversions I've had. Great job.

The tweaking of an icon

My dad gave me my first BUCK hunting knife 45 years ago and said then that there is more expensive knives out there and maybe a few prettier one's but as far a quality, reliability and durability you can't do any better then a BUCK. well for the last 45 years I must say he was right in all accounts. I have several 110 folding hunters as well as several 112's and a verity of Skinner and small pocket knives (all BUCKS of course) and they do stand the test of time. There warranty is second to none even though I have only had to use it once or twice over the many years, they honor their product as advertised. And now with the 110 Auto, well they hit a home-run with this one, it's the same robust high quality 110 that we have come to know and love with a few more internal parts. It opens with authority and locks tight. The price is a little high in my opinion but the way this knife is going to catch on it will be another BUCK treasure I'm sure in no time.

Buck 110 Automatic

Smooth action, fast opening coupled with that quality you expect in a Buck knife. Comes with a Leather sheath which is a nice touch, the blade is razor sharp, overall super high quality with a modern touch being able to open it with one hand.
