Why Professionals Choose the KN-240 Series for Mission-Critical Operations

⏺︎ The KN-240 is designed as an extreme-environment tool platform, offering a singular advantage in structural integrity where tool reliability is absolutely non-negotiable.
⏺︎ Structural Integrity: The Full Tang Advantage.
⏺︎ Unlike many utility knives on the market where the steel blade ends abruptly and is simply inserted into a plastic or composite handle, the entire KN-240 series is built with a full-tang, monolithic construction.
⏺︎ Unmatched Strength: The steel of the blade runs uninterrupted through the entire length of the knife, forming the handle foundation (full tang). This single-piece construction ensures superior strength, eliminating failure points often found where a blade is merely pinned or bolted into a secondary handle material.
⏺︎ Reliability: This design guarantees that the knife can withstand extreme lateral force, twisting, and heavy-duty tasks like batoning, without the risk of the blade separating from the handle—a critical factor in high-stakes operational environments.

Extreme Amphibious Capability: The KN-240S Series (Diving & Maritime). Dedicated Material: The KN-240SC/SP utilizes SUS 420J2 Stainless Steel for its superior immunity to salt-water corrosion. This ensures that the entire steel core remains structurally sound, even in marine environments. Operational Options: Users choose the durable Chrome Coating (SC) or the non-reflective Powder-Coated Black Sandblasting finish (SP) for low-visibility infiltration.

Versatility & Edge Integrity: The KN-240A Series (Tactical & Outdoor). High-Performance Steel: The KN-240AC/AP models feature SUS AUS-8 Stainless Steel, offering excellent edge retention and ease of maintenance in the field. Finish Adaptability: Available in bright Chrome Coating (AC) or the tactical Black Powder Coating (AP), which provides an anti-glare finish essential for minimizing light signature. Summary: Precision vs. Compromise The KN-240 platform offers the professional an assurance of uncompromised structural reliability. When success hinges on the strength of your tool, choosing a full-tang, single-piece steel construction over cheaper, composite designs—where materials might be plastic painted to resemble metal—is the only logical choice.
