Benchmade 3370GY-1 Claymore Auto OTF 3.89″ CPM-D2 Smoke Grey Double Edge Dagger – Ranger Green Grivory

The Benchmade 3370GY-1 Claymore Auto OTF is a 3.89 inch CPM-D2 double edge dagger in smoke grey, housed in a Ranger Green Grivory handle, and it exists for people who want serious out the front performance without a heavy knife on the belt. It is known for its iconic ball bearing matrix texturing, lightning fast automatic actuation, and strength and durability through hard use tasks. This is a working OTF, not a novelty.

Out the front knives have a reputation for being fragile. The Claymore was designed to answer that directly, with a lightweight handle wrapped around a genuinely capable blade.

What the Benchmade 3370GY-1 Claymore Auto Delivers

The out the front configuration features a slider release button and a double edge CPM-D2 dagger housed in a lightweight Grivory handle, giving ambidextrous confidence in stressful situations and hardcore utility the rest of the time. The slider sits where either thumb can find it, so left handed users are not compromising with a knife built for someone else.

This one goes to people who want powerful tactical self defense and performance from a compact package. That means duty carriers, outdoors users who want deployment without fumbling, and knife enthusiasts who appreciate a well executed OTF. The Claymore family also lets you choose between Black or Ranger Green handles and a plain edge or the oversized dual serrated blade, and this listing is the Ranger Green Grivory version.

Key Features

• Out the front automatic action with lightning fast actuation for immediate single hand deployment.
• Slider release button that operates comfortably from either side for true ambidextrous use.
• Double edge dagger blade ground from CPM-D2, a tool steel chosen for edge retention and toughness.
• Lightweight Grivory handle that keeps carry weight low without giving up rigidity.
• Iconic ball bearing matrix texturing that holds grip security in wet or gloved hands.
• Smoke grey blade finish paired with a Ranger Green handle for a subdued, field appropriate look.

Blade Steel, Dimensions, and Handle Material

The blade measures 3.89 inches, which is long enough for real utility and defensive work while staying manageable in an OTF platform. CPM-D2 is a powder metallurgy version of a proven tool steel, and the powder process gives a finer, more uniform grain than conventional D2. In practice that means better toughness at the edge and more consistent sharpening behavior.

Grivory is the other material story. The Benchmade 3370GY-1 Claymore Auto uses it because it is light, dimensionally stable, and resistant to the solvents and temperature swings that destroy cheaper polymers. Combined with the ball bearing matrix texturing, the handle stays in your hand when your hand is not cooperating.

Deployment, Maintenance, and Compatibility

Out the front knives reward disciplined handling. Deploy with the knife clear of your body and your support hand well away from the muzzle end of the handle, and let the action do the work rather than helping the blade along. Retract fully every time so the blade seats and locks instead of sitting partially withdrawn in the channel.

Keep the internal channel clean. Lint, sand, and pocket debris are the main enemies of OTF reliability, so blow the channel out with compressed air periodically and avoid carrying the knife loose in a pocket full of grit. A drop of light lubricant on the moving parts, worked through a few cycles, keeps the action crisp without attracting dust.

Sharpening a double edge dagger takes patience because you are maintaining two symmetrical grinds. Work each side evenly with a stone or guided system and keep the angles consistent so the point stays centered. Wipe the smoke grey finish down after handling rather than scrubbing it, and dry the blade fully before retracting it into the Benchmade 3370GY-1 Claymore Auto handle.
