TUKK gunmetal gray

This was my first TUKK. Super lightweight and utilitarian. Unlike a pocket folding knife, this is much more discrete when used in a public / office setting. Fun to fidget with too. Since the blade does not lock open, took a couple minutes to get used to. Great tool, highly recommended!

Cool little knife

I love my TUKK. Construction is amazing. This thing will last a lifetime!
I deducted one star because I find it difficult for my thumb to “grip” the slider. If it was a micron or 3 thicker it would be perfect. But the recessed slider is also what keeps it from accidental deployment. Also it’s a little difficult to position in the hand based on feel/muscle memory. All those times you blindly pull out a knife to open something while people are talking.
I carry it every day and use it often to open packages at work. Despite the warning, I carry it in my pocket. I’m an adult and can accept responsibility if I choose to not follow the rules. I have had no accidental deployments so far.

Design & Utility Brilliance

The TUKK has been a revelation for me, I was sceptical that such a small blade would be useful, but wow it’s amazing. I use it everyday at work to cut cardboard boxes, plastic packaging and other small tasks. It has pretty much become my primary work knife. It’s also completely UK legal to carry so I will never be without a bade ever again. Brad I doff my cap to you sir for producing this truly excellent example of industrial design.


I have been following Tactical Keychains for quite some time. Every tool that Brad makes is worth the money.
I finally got me a TUKK. I Love it. It’s great to have a small knife for opening things instead of filling my EDC knife. I would recommend the TUKK to anyone that’s looking for a product that’s made with pride and works the way it’s supposed to.

Best purchase ever

I can't tell you how much this has improved life, I can't think of many things I own that bring me this much joy everytime I use it. I never experience existential angst anymore while struggling with packaging, and I'm no longer ostracized by society for carrying around giant pocket knives. All jokes aside, this is an amazing product from Brad and I can't wait to get my hands on the titanium version!
