Premium Blade Material & Deployment Mechanism
The MT Customs Green 150-10 Halo VI OTF AUTO Knife features a full-length 4.17″ blade crafted from Elmax steel—one of the advanced powder-metallurgy steels known for exceptional wear resistance, corrosion resistance and excellent edge retention. The blade is configured in an OTF automatic mechanism (out-the-front), meaning the blade extends directly from the front of the handle via a switch or slider, enabling one-hand rapid deployment. The automatic action is smooth, reliable and designed to deliver swift access when seconds count. The Elmax blade’s large size and premium steel grant the knife serious performance credentials: strong thrust capability, confident slicing, and long-term durability under regular use or demanding conditions.
Lightweight Aluminum Alloy Handles & Ergonomics
Complementing the premium blade is a rugged aluminum alloy handle assembly finished in a rich green tone. The aluminum alloy offers a substantial strength-to-weight ratio—meaning you get robust structural support without excessive bulk or carry weight. The machining and finishing on the handle include refined contours, texture for grip retention and visually striking accents that highlight the Halo VI styling. The ergonomics have been refined to support secure handling during rapid deployment, manipulation and retention under movement. The combination of premium materials, precise machining and ergonomic design ensures that the handle matches up with the high-performance blade and mechanism.
Versatile Tactical & Collector Appeal
Although designed with tactical readiness in mind, the MT Customs Green 150-10 Halo VI OTF AUTO Knife also appeals to collectors and premium knife aficionados. Its large 4.17″ Elmax blade, automatic deployment system, and signature Halo VI styling make it a centerpiece of any collection. At the same time, the build quality and materials mean it’s capable of use in serious scenarios—whether that’s outdoor utility, security carry, or preparedness tasks. The green alloy handle finish gives it distinctive aesthetics, while the OTF action ensures functional performance. This knife bridges the gap between showpiece and tool, offering form and function in one unit.

Product Advantages
• Superior Blade Steel & Size
Using Elmax steel for a 4.17″ blade gives this model outstanding edge retention, wear resistance and corrosion performance. Many knives with similar sized blades use lower grade steels; here you get high-end materials. The length and profile of the blade allow for serious utility work, tactical readiness and presentation value. This means you’re equipped for both demanding tasks and collector display without compromise.
• Quick One-Hand Automatic OTF Mechanism
The out-the-front automatic deployment gives fast, one-hand access to the blade—a key advantage in tactical or emergency scenarios. The mechanism is designed for reliability and repeatability – each deployment should feel crisp and secure. For a user who values speed and readiness, this mechanism elevates practical function beyond standard manual knives. It also adds an element of sophistication and engineering worth appreciating for collectors.
• Lightweight and Durable Aluminum Alloy Handle
The handle is built from high-grade aluminum alloy, offering durability under stress while keeping carry weight manageable. The green finish adds visual appeal and corrosion resistance, while the ergonomic contours and textured surfaces ensure secure grip even in rapid deployment or dynamic use. The handle’s precision machining and material choice speak to premium construction and long-term resilience.
• Aesthetic & Functional Hybrid for Enthusiasts and Operators
The Halo VI design aesthetic, green aluminum handles and large Elmax blade place this knife firmly in the premium category for enthusiasts. At the same time, the functional readiness—automatic deployment, robust materials—makes it viable as an operational tool. This dual identity means it serves both as a display piece and a workhorse tool, providing value in multiple use-cases.
• Value for Premium Features
While many knives with Elmax blades, automatic OTF mechanisms and beat-out handles cost significantly more, the MT Customs Green 150-10 Halo VI offers access to these premium features in a refined package. For users seeking high-end performance without custom-price economics, this model delivers strong materials, refined build and mechanized action in one. A serious investment for those who understand knife performance and value.
Usage Scenarios
• Everyday Carry (EDC) for Premium Users
For the user who demands more than just a basic EDC knife, this model brings readiness, performance and style. In daily tasks such as opening packages, cutting cord, prepping materials or light utility work, the 4.17″ Elmax blade offers more capacity than typical EDC blades. The automatic deployment enables rapid access, while the green aluminum handle gives a premium look in the pocket or on a carry clip. Ideal for someone who values high quality, readiness and aesthetics in their everyday tool.
• Tactical / Security / Operational Use
In professional or security roles where speed, reliability and strength matter, the MT Customs Green 150-10 Halo VI OTF AUTO Knife is well suited. The automatic mechanism provides immediate blade deployment, the large Elmax blade offers serious cutting capability, and the durable handle supports secure handling in dynamic environments. Whether used for response tasks, field interventions or equipment carry, this knife offers both form and function for the serious operator.
• Outdoor & Field Utility Tasks
When heading out into the field—camping, hiking, hunting, or general outdoor work—the robust build of this knife stands up to environment pressures. The corrosion-resistant Elmax blade, strong handle materials and automatic deployment system provide a tool that can handle cutting rope, preparing gear, shelter building, or emergency tasks. The size of the blade offers more versatility than a typical compact folder, yet the handle keeps carry manageable.
• Collector & Display Piece with Use-Capability
For knife collectors and enthusiasts, the Halo VI styling, Elmax blade and green aluminum finish make this model a standout. While designed for practical use, it also makes an eye-catching showpiece. Displayed alongside other high-end automatics or fixed blades, it brings both visual appeal and real-world performance. Collectors who appreciate action mechanics, premium steel and refined handle material will find this blade appealing.
• Gift for Gear Enthusiasts and Professionals
If you’re selecting a gift for someone who values precision gear, knives or tactical tools, this model is an excellent candidate. The combination of high-performance materials (Elmax, aluminum alloy), automated deployment, and refined design gives something beyond standard offerings. Whether for a professional user, gear collector or someone entering premium knife territory, this is a thoughtful, high-quality gift with function and flair.
