Spartan Blades CQB Tool - Ring Dagger for Close Quarters Carry

The Spartan Blades CQB Tool is a ring dagger - a specific category of tactical fixed blade knife designed for close quarters battle, defensive carry, and firearms transition work. Ring daggers are purpose-built around a single index finger ring that locks the blade into the hand without requiring a conscious grip, keeping the blade available while the fingers remain free to operate a firearm, open a door, or control a threat. The CQB Tool is the most field-proven ring dagger in production today, and it has a direct line to the US Army Special Operations Forces combatives program that defined the category.

Before the Benchmade SOCP dagger existed, there was the Spartan Blades CQB Tool. Greg Thompson - founder of H2H/Team ROC at Fort Bragg and developer of the Special Operations Combatives Program for US Army Special Operations Forces - brought his CQB ring dagger concept to Spartan Blades first. Working alongside Spartan founders Curtis Iovito and Mark Carey, and a former Special Forces unit at USAJFKSWCS, Thompson and the Spartan team engineered the original production version of this design from the ground up. What came out of that collaboration is a close quarters battle knife that remains one of the most field-proven tactical fixed blades available today.

What is a ring dagger - and who carries one

A ring dagger - also called a finger ring knife, CQB tool, or transition knife - is a compact fixed blade self defense knife built around a full-diameter finger ring rather than a conventional grip. The ring passes over the index finger and the handle nests against the palm, creating a retention system that cannot be broken by impact, grabs, or adrenaline-induced grip failures. Unlike a conventional fixed blade that requires an active fist to retain, a ring dagger stays in the hand passively - freeing all four fingers for any secondary task while the blade remains available for immediate use.

Ring daggers are primarily carried by military operators, law enforcement, and first responders as secondary defensive blades - carried behind magazine pouches on MOLLE/PALS platforms or inside the waistband as a backup when the primary weapon is down, transitioning, or out of reach. Because of their minimal profile and light weight, they have also found a strong following among civilians who want a serious concealable self defense fixed blade for everyday carry. The Spartan Blades CQB Tool is the standard by which most other ring daggers are judged.

Who makes the Spartan Blades CQB Tool

Spartan Blades was founded in 2008 by Curtis Iovito and Mark Carey - two retired US Army Special Forces NCOs with over 40 years of combined Special Forces service between them. They started the company in a pre-Civil War mule barn in Southern Pines, North Carolina, with the specific intention of building knives that reflected genuine field experience rather than marketing assumptions. Every knife in the Spartan Blades Gold Line - the full production lineup we carry at KnifeArt - is 100% made in the USA, built to the tolerance standards of people who have carried blades in real-world conditions. The CQB Tool is the most direct expression of that mission - a close quarters battle knife developed in direct collaboration between Spartan's founders, Greg Thompson, and a former Special Forces unit at USAJFKSWCS (the US Army John F. Kennedy Special Warfare Center and School at Fort Bragg). That collaboration is documented by Spartan Blades and confirmed across multiple authorized dealer channels.

What the CQB Tool is designed to do

The CQB Tool is a transition tool - not a utility knife, not a general purpose fixed blade. It is designed for one specific situation: a close-quarters grapple where your primary weapon is unavailable, compromised, or in transition. The finger ring locks the blade into your hand completely - once your index finger is through the ring and your hand is closed, the knife cannot be taken from you, cannot be dropped under stress, and does not require any conscious grip maintenance. Your hand is free to push, grab, and control while the blade remains available. The slim profile and low height on the MOLLE/PALS platform mean it stows behind a magazine pouch or front panel without printing or interfering with primary weapon access.

Greg Thompson designed this CQB ring dagger specifically for the US Army Special Forces combatives program, and that program specificity is exactly what makes it so effective for law enforcement, first responders, and serious defensive carry users who have thought carefully about what a backup fixed blade actually needs to do on their kit.

Spartan Blades CQB Tool - specs and features

The CQB Tool is available in two finish options - Tungsten DLC Black and Flat Dark Earth (ZrN) - each with a matching color Kydex sheath. Both are built to the same specs from the same materials. Choose Black for standard low-visibility carry; choose FDE for desert environments or to coordinate with tan gear.

154CM steel and double-deep cryo treatment

The blade is 154CM stainless steel - a high-carbon, high-chromium tool steel with an excellent combination of edge retention, corrosion resistance, and toughness at the 57-59 HRC range. Spartan subjects every CQB Tool blade to a double-deep cryogenic heat treatment - a two-stage process that drives the transformation of retained austenite deeper into the steel, producing more uniform hardness, better edge stability, and improved toughness throughout the blade.

SpartaCoat PVD finish

The SpartaCoat PVD coating - Tungsten DLC on the black version, Zirconium Nitride (ZrN) on the FDE - bonds at the molecular level for superior adhesion, corrosion resistance, and low-glare finish in the field. DLC (Diamond-Like Carbon) is among the hardest surface coatings available for knife blades, offering abrasion resistance well beyond standard cerakote or parkerizing.

Form-fitted Kydex sheath

The included Kydex sheath is contoured specifically to the ring geometry of the CQB Tool - not a generic fixed blade sheath adapted to fit. It mounts behind front magazine pouches or other MOLLE/PALS panels for completely concealed carry within the gear stack, or runs on a belt or inside the waistband for plainclothes and off-duty use.

Spartan CQB Tool vs Benchmade SOCP - two ring daggers, one lineage

Both the Spartan CQB Tool and the Benchmade SOCP dagger belong to the same category of ring dagger tactical fixed blades, and both trace directly to Greg Thompson and the same SOCP combatives program. The Spartan came first - developed in direct collaboration between Thompson, the Spartan founders, and a Special Forces unit at USAJFKSWCS. The Benchmade SOCP followed as a separate production arrangement. The two designs share the same fundamental finger ring dagger geometry and transition tool philosophy, with meaningful differences in steel, coating, sheath design, and price.

The Spartan CQB Tool is built from 154CM with double-deep cryo treatment and SpartaCoat PVD - and it is made by a company founded by Special Forces veterans who built the knife alongside Thompson from the beginning. For buyers who want the original collaboration and want to support a veteran-founded American-made knife company, the Spartan CQB Tool is where that story starts. We carry both on KnifeArt.com - if you want help deciding which ring dagger is right for your carry setup, call us at 800-564-3327.
