We didn’t just design a knife — we shrunk it to keychain size without losing an ounce of power. Meet BITZ: the world’s smallest fully functional knife, featuring an ultra-tough tungsten blade and a precision-machined titanium or brass body. It’s sleek, strong, and ridiculously compact.

At the core of BITZ is what truly matters: the blade. Crafted from tungsten alloy — one of the hardest and most expensive materials in modern blades — BITZ cuts far above its weight class.

With a Mohs hardness of 9, tungsten delivers superior edge retentionunmatched toughness, and clean slicing power. It’s the same material trusted in surgical tools and industrial-grade cutters. Nothing else this small should cut this well!

No twisting. No clips. No delay. Magnetic Quick-Release for Lightning-Fast Access.

BITZ features a powerful neodymium magnetic connector that detaches and reattaches in a snap — literally.

  • Pull to release with one hand
  • Cut instantly — no fumbling, no friction
  • Snap it back with magnetic precision

At only 4.8cm long, BITZ is one of the smallest functional knives ever made — but don’t let the size fool you. It disappears on your keychain, necklace, zipper pull, or in your coin pocket, yet delivers real, full-force cutting performance the moment you need it.

BITZ is built to last a lifetime. Choose between Grade 5 Titanium and Solid Brass — both CNC-machined for precision, strength, and character. Whether you want modern minimalism or vintage charm, BITZ delivers premium materials with purpose.

BITZ-Ti – Ultra-light, corrosion-resistant, and made for daily abuse.

BITZ-Brass – Heavier, richer in tone, and develops a warm patina over time.

BITZ is more than a tool — it’s a statement of style and substance. Each version features one of four signature laser-etched designs:

  • Frost – Icy, crystalline texture for a sleek and refined look.
  • Core – Smooth and minimal, pure metal in its rawest form.
  • Hive – Bold hex pattern for a tactical, geometric edge.
  • Spine – Woven, organic lines inspired by nature and structure.

BITZ is made to ride on your keychain and vanish into your carry — until the moment you need it. No bulk. No hassle. Just a sharp, ready blade that’s there when it counts.

  • Magnetic keychain base = fast access, secure hold
  • Replaceable blade = lifelong utility
  • Lightweight, ultra-compact form = true EDC readiness
