Introducing – The Zipper
The Zipper is one of my favorite design. In a way, all my designs are my favorite. But I really like the zipper. I am especially happy with the way the raised texture came out. I chose to have the texture “raised” by 0.5mm. Quote and unquote raised because the factory had to CNC off the entire layer and just leave the texture. It was hard to find an OEM that was willing to do that and still keep the cost relatively acceptable for me.
Zipper is very snappy. I think the size is just perfect for an OTF Box Cutter. The Zipper is designed to be a workhorse for everyone.
The Zipper is designed with deep pocket carry and reversible carry. So everyone can abuse the heck out of it destroying those Amazon boxes!!

Really impressed with the quality of this knife. Solid build with good materials and the action is smooth. Highly recommend!
Great knife I’ve been using it every day at work to open boxes 📦
Great blade!! Feels sturdy in my hand and the quality is evident when you hold it. Great fit and finish. AA++!!!!
100% lock up, solid feel, great texture, compact to save valuable pocket real estate.
This is a highly useful tool with all the fidget factor satisfaction an OTF has to offer. Blade changes are a breeze, and the size is perfect.
