I found it to be useful and very high quality.best buy in a long time

When I originally ordered this I thought I ordered the Zero-G, then I realized that I got the Zero. I needed one for work anyway. I’m so pleased that I did, this an amazing piece of machine work! It’s so smooth and as easy as pie to open, close and remove the blade! I don’t believe there’s a better knife out there, at least until the Zero-G comes out(pocket clip rules all)! Thank for amazing product

Love it! Compact and practical.

So cool! Thanks RiveryMFG! Now i need 2.0!!!!

Excellent knife holder, fits a hooked blade if you break one side. Pulling back to the retract position and performing a pull cut acts as an auto retract safety.
Easy website to navigate. Multiple ways to pay makes it nice and easy.

This has got to be one of the coolest things I’ve ever owned! The action is flawless and smooth. Just the right size to carry in your pocket and even your fifth pocket. Works great when cutting down boxes, opening packages and working around the house.

I love it, perfect for edc

Really love this thing it is so cool proud to have it in my pocket

Pretty fun and functional
good quality product , as advertized. I will be purchasing more .

This thing is just as good as you think it’s going to be. So much fun to use.

I'm 63 with arthritis. I do not have the grip strength of a young person but still need to cut things. The first hour after the zeros arrived I had difficulty using one. I left one out on my desk that day and just kept opening and closing the thing best I could. By the next afternoon I could use it just fine. It now works like it should and I am very pleased. I would recommend.

Anazing. Love this product. Well thought and executed.

We came across Rivery at Blade Show ATL this year(2025) and we were enamored from the jump. The simplistic design, the smooth action, the well done colors, it all just works. Instantly had to add them to our website and our customer are responding well. The guys are great to boot. These are a no brainer, get one, love one, thats it.

Surprisingly Addictive
Zero is hard to leave alone once it's in your hand. It's something about the clicks and haptic feel of the retract. On extension, the internal mechanism makes a really satisfying click due to the beefy key snapping into the locked position.
-
Seamless and Screwless
We devoted many hours and several iterations to create a design that does not use screws and does not require a tool to disassemble. Some of the internal mechanism is similar to the tricks used inside a mechanical puzzle.

Blade Compatibility
Zero is capable of accepting various blade types from most major manufacturers.
