6 sold in last 24 hours
This dual-action OTF knife is for buyers who want more than blacked-out tactical. The Spectrum Surge launches a 3.625" double-edge dagger blade on command with a firm, positive slide—then locks up with authority. Rainbow titanium coating on both blade and handle delivers standout style, while the metal chassis, glass breaker, and pocket clip keep it firmly in the working-EDC category. If you’ve been waiting to buy an OTF knife that looks custom but feels reliable, this is the one.
OTF Knife for Sale with Dual-Action Confidence and Rainbow Titanium Finish
The Spectrum Surge Dual-Action OTF Blade - Rainbow Titanium is for buyers who already know they want a real automatic OTF knife for sale, not a novelty.

Why This OTF Knife for Sale Deserves a Spot in Your Pocket
If you're ready to buy an OTF knife, you’re comparing three things: action, build, and carry. The Spectrum Surge checks each box with details you can feel on day one.
- Action: True dual-action automatic OTF — thumb slide forward to deploy, back to retract, with a consistent spring feel.
- Build: Full metal handle with titanium finish, secured by Torx hardware, designed to take real pocket time.
- Carry: Deep-carry pocket clip, glass breaker tip, and a 9.4 oz weight that feels solid without being unwieldy.
This is an OTF knife for sale aimed at buyers who want operator-style function with standout rainbow titanium looks — not a toy, not a trainer, but a working automatic OTF knife.
Build Quality: What You’re Really Getting When You Buy This OTF Knife
With any OTF knives for sale online, the real question is whether the action and lockup will still feel tight after repeated use. The Spectrum Surge is built around a steel dagger blade and a metal handle chassis, paired with a proven dual-action slide mechanism.
Blade Details That Justify the Purchase
- Blade length: 3.625 inches — long enough for real cutting, still pocket-carry legal in many areas.
- Blade style: Double-edge dagger with central fuller for balance and reduced weight.
- Blade edge: Plain on both sides for clean slicing and easy maintenance.
- Blade material: Steel chosen for everyday carry use — holds a working edge and sharpens without fuss.
- Blade finish: Rainbow titanium coating that resists corrosion and wear while delivering that iridescent pop.
The dagger profile, combined with the double-edge grind, gives you piercing capability and consistent cutting performance whether you’re opening boxes, slicing straps, or adding a statement piece to your OTF collection.
Handle, Grip, and Everyday Control
- Handle material: Full metal construction with a rainbow titanium finish to match the blade.
- Grip: Textured inlay panels provide traction so the knife stays put during deployment and use.
- Actuator: Side-mounted thumb slide positioned for natural, one-handed operation.
- Glass breaker: Integrated tip at the butt for emergency use and added tactical utility.
- Pocket clip: Deep-carry style clip for discreet, secure pocket carry.
The 9.4 oz weight and 5.75-inch closed length give the Spectrum Surge real presence in hand. It feels like a full-size tactical OTF, not a lightweight novelty.
