HYPER-THIN KNIFE
Introducing a pocket knife that is the size of a credit card. Every part of this knife is engineered to look, feel, and perform as you need and want. It’s a multitool as well, with multiple features for everyday use. With our FlyOff design if you ever forget to put this in your checked luggage when flying, you can surrender the blade at TSA and replace it for just a few dollars.
FEATURES
The HT-420 will surprise you with its thinness. Its satisfying locking mechanism speaks to its craftsmanship. Gripping the handle with the blade open, gives you confidence you didn’t expect from holding such thin metal. Its strength - despite having so little material - is surprising.
FlyOff Blade
Our patented FlyOff® pivot enables you to remove the blade quickly, easily, and without tools. If you forget to put your HT-420 in your checked luggage when traveling and you get stopped at airport security, you can simply surrender the blade. Add replacement blades now or come back later when you need them.

ADDITIONAL TOOLS
The HT-420 makes full use of the card-shaped profile. Every edge and square inch is utilized as a knife feature or as a tool.
- Knife
- Prybar
- Screwdriver tips
- Bottle Opener
- Inch Ruler
- Metric Ruler
People often misuse their knives as a screwdriver or as a prybar, so these features are built right into the handle. Of course, it wouldn't be a Zootility Co. design without a bottle opener. Rulers can often come in handy, so we made the straight edge an inch ruler on one side and a metric ruler on the other. All of these features are integrated into the fully-hardened stainless steel construction, creating a rigid and safe knife with a solid feel and exceptional durability. All the markings are fiber laser engraved to ensure the highest quality mark possible.
