Twist to Lock. Twist to Release.

The MRF Fold is the first folding knife built around the MRF Rotate Lock™ — a proprietary dual-tab locking mechanism designed and engineered in-house. No liner lock. No frame lock. Something entirely new.

One twist locks the blade dead solid. Another twist releases it. One-hand operation. Zero blade play.

🔒 MRF Rotate Lock™ — What Makes It Different

The Mechanism:
A CNC-machined rotating disc with two symmetrical locking tabs sits at the pivot axis. When you twist the disc, the tabs engage precision-cut grooves in the blade tang and a locking pin secures the blade in the open position.

Why It Matters:
Traditional locks (liner, frame, back lock) rely on spring tension — they wear over time. The Rotate Lock uses positive mechanical engagement: metal tabs physically blocking the blade from moving. No springs to weaken. No play to develop.

One Hand:
Twist the disc with your thumb. That's it. Open, lock, unlock, close — all one-handed.

🎁 For The Knife Person Who's Seen Everything

Every knife brand uses the same three locks: liner, frame, back lock. The MRF Fold is the first production knife with a rotating disc lock. If you collect knives, this is the one nobody else at the meetup will have. If you use knives daily, this is the lock that won't develop play after 10,000 cycles.

⚠️ Custom Side Plates

Side plates can be produced in any Cerakote color or pattern. Contact us at info@mrf.tools for custom colors, corporate branding, or bulk orders.
