USA Knifemaker Supply Kwik Thumb Stud Black Oxide

This works very well with my Silver Stag Lion Liner Lock knife. It also works ok on my Otter Mercator brass lock back knife, but not the steel one. It did not work at all on my Buck 110 folder, which according to the symbol on the blade was made in 1996. But it's just too thick for the thumb stud to stick out far enough from the blade. Some other knives I tried it on, I couldn't get it to work. It all depends on the positioning, the thickness of the knife scales, and the stiffness of the opening mechanism. Once attached it is secure, though.

I have a knives of Alaska featherweight hunter and this works perfectly on it. I love the knife but it can be a little difficult to open quickly. This makes all the difference. Highly recommended.

I love it, but it could slim dow, some millameters

I ordered the Kwik thumb studs for my Buck 110 because of Cutlery lovers review on YouTube, I have to say it was a great purchase. Super easy to put on and make the 110 go from a two handed opening knife to one handed. And they also look good on the knife. I'd absolutely buy again.

Turned my Civivi Elementum into a brand new figity knife! I love it

Those Buck 110's ain't gonna one-hand open if you are buying the LT line. These are a sturdy way to add a thumb stud to a classic. Love the black oxide look. They arrived promptly and were a breeze to install.

Awesome invention great purchase/ bought a few and looking to buy a few more I put one of them on my LEATHERMAN K2 Blade 💯% worth the money- takes a knife that you love but can’t carry due to not being able to deploy the blade easy / with this system I had a thumb stud on in less then a minute- comes with mini Allen Key to put on in the spot you prefer ‼️✅ Look at the black knife top left corner 👍🏼🤜🏼🇺🇸🤛🏼💪🏼

Works great for my every day carry 110 knife.
