BITZ Knife – The World’s Smallest Knife

BITZ Knife – The World’s Smallest Knife with Real Cutting Power

The BITZ Knife is more than a novelty—it’s a precision EDC essential engineered to punch far above its micro-sized weight class. At just 47.5mm in length, it’s barely larger than a house key, yet this magnetic quick-release knife is built to slice with surgical efficiency. Created by YSMART, the proven Kickstarter powerhouse behind a dozen-plus everyday carry triumphs, the BITZ Knife combines minimalist design with elite-level materials, giving it a serious edge—literally and figuratively.

Don’t let its diminutive profile fool you. The BITZ Knife is crafted with a tungsten alloy blade that rivals industrial cutting tools. With a Mohs hardness rating of 9, this blade delivers serious edge retention, ready to make quick work of cardboard, nylon straps, zip ties, and even light electrical cable. It’s the kind of cutting power you’d expect from a full-size blade, scaled down for daily deployment on your keychain, bag zipper, or even around your neck.

What truly sets the BITZ Knife apart is its neodymium magnetic quick-release system. A gentle tug separates the cap and blade, giving you one-handed, split-second access—no fumbling, twisting, or pocket digging. It’s a feature that feels as intuitive as it is innovative, giving users the confidence to act swiftly in real-world scenarios, from field fixes to daily packaging cuts. Snap it off, use it, click it back—repeat.

BITZ Knife – Built Tough with Titanium, Brass, and Style

The BITZ Knife is available in two premium materials. BITZ-Ti is crafted from Grade 5 titanium, giving it the featherlight durability ideal for active users. Prefer something with a little more heft and character? The BITZ-Br version, built from solid brass, gains a rich patina over time—perfect for those who love gear that tells a story.

Beyond its body materials, the BITZ Knife adds visual and tactile appeal with four laser-etched surface finishes. “Frost” offers an icy crystalline aesthetic, while “Core” keeps it sleek and minimalist. The “Hive” pattern delivers a geometric, tech-forward vibe, and “Spine” evokes an organic texture that hints at strength and structure.

Functionally, it’s built to last—and to stay sharp. The blade is easily replaceable without tools, keeping waste and maintenance to a minimum. The magnetic base attaches effortlessly to keyrings, bags, or utility lanyards, ensuring the BITZ Knife is never out of reach. It’s a tool designed to disappear into your carry until it’s time to cut—and then it shines.
