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!!

This is a very nice Otf …. Great quality!
I’ve been debating on whether or not to pull the trigger on this knife and I’m so glad I did. I use a lot of tape and deal with a lot of boxes for work and don’t like getting the glue and stuff from them on my regular pocket knives. This knife is so clutch when it comes to those and the action is so fidgety and I can’t get enough when deploying it. One of my best purchases this year, great job with the design and execution guys!!!
Loving this knife! Didn’t realize how much fun and function this OTF tool would have. BTW, the Arrow brand replacement utility blades have worked best for me.
It is incredible. The quality is amazing. It feels good. No miss fires. Decently weighty but not too heavy. Exactly as described.
The knife seems well built and solid. It has smooth action and the blade is nice and tight when deployed, indicating good engineering tolerances. The only problem I have is the shipping. USPS is hot garbage and should only be used for bills and junk mail.
