Handy little bugger

Received my TUKK recently. I got the copper version and I absolutely love it. Just wish I could get a titanium TUKK but unfortunately these are no longer available. The blade sometimes stick but as mentiomed with the product instructions, it may need a break in period.


I have an addiction to finely machined tools. The copper TUKK joins my TUKK-XL and WTF, more to come.
Shipping and service was excellent.

Nice material-finish, works great

Got two titanium TUKK three years ago together with the Ti-MQR on Kickstarter in 2015. Now my son wanted a different one for himself. He will get it on his birthday next tuesday.

Gotta have more than one!

Had two of the first titanium version tukks, but gave one to a friend and regretted it. Now that it will be discontinued I purchased 2 more brass tukks. It's one of the most convenient cutting tools for your keychain or light carry. The quality is simply outstanding. Brad has created one the best little tools, which is sure to be a classic. Go get some before they're gone!


This is truly a beautifully constructed piece. So far I have two TUKKs: one is brass and another in titanium. They’re the perfect 5th pocket companion. Perfect for the small jobs I do around the house. I hate to see these being discontinued, but I’m so glad I was able to purchase one before they’re gone. Great work Brad!
