Product Description
The Kershaw Interval 1399 is a centerpiece of the innovative Project ATOM series, offering a full-sized fixed blade profile with almost zero weight. Engineered for environments where traditional steel might be a liability—such as high-corrosion marine settings or ultra-lightweight backpacking—the Interval is crafted entirely from a high-strength PA-66 nylon and glass fiber composite. This specialized material ensures the tool is completely rust-proof, non-magnetic, and incredibly durable, providing a reliable utility option that thrives where metal tools fail.
Measuring 7.4 inches overall, the Interval features a substantial 3.5-inch drop point blade. While the edges are purposefully blunt for safe handling and carry, the reinforced tip is designed for effective piercing and light prying tasks. Despite its larger form factor, the Interval weighs a mere 0.7 ounces, making it lighter than a standard house key. Whether you need a low-maintenance backup tool for your tackle box, a lightweight self-defense option for trail running, or a stealthy utility blade for a bug-out bag, the Interval delivers maximum simplicity with minimal mass.
