The Unilite EK4 Heavy Duty Folding Knife is built for the real world—where toughness, reliability, and one-handed usability matter. Centered on a high-carbon 3Cr13 stainless steel blade, this knife delivers steady edge retention without weighing you down, while the ultra-tough aluminum handle stands up to daily wear and tear.

Designed for precision and control, the drop point blade pairs a serrated edge with a tapered spine swedge. This combo means you can slice through tough materials like rope and cordage, then switch to lighter, more controlled cuts with the tip. A thumb rise on the blade spine and two wire stripper notches give you confident, versatile grip in all conditions, from wet environments to tight working spaces.

Unmatched practicality in a compact tool

• Assisted one-handed opening with thumb studs for quick deployment, even when your other hand is occupied.
• Framelock mechanism securely locks the blade in place during use, reducing the chance of accidental closure.
• Ergonomic aluminum handle with a front quillion finger guard for added safety and comfort during extended use.
• Pocket clip for secure carry and easy access on the job site or in the field.
