The Core Edge USA 0331 Pulsar OTF is built for those who want serious performance packed into a lightweight, precision-machined package. As the most popular model in Core Edge USA’s 0331 line, the Pulsar combines rugged materials, practical design, and unmistakable style in an out-the-front automatic platform. Its chassis is precision machined from 6061-T6 aluminum and features 3D milling across the front and back faces, creating a textured surface that adds visual depth while providing a secure, confident grip. The purple anodized finish gives this Pulsar a bold look without sacrificing the hard-use character expected from a purpose-built OTF.
At the business end, the 3.350-inch single-edge drop point blade is crafted from MagnaCut stainless steel, giving the Pulsar a premium blade material well suited for everyday cutting tasks and demanding use. The blade combines a blasted finish with satin flats for a distinctive two-tone appearance that complements the purple chassis. Its single-edge configuration provides a practical cutting profile, while the automatic OTF mechanism delivers rapid, convenient deployment at the push of a button. Whether it’s carried as an everyday cutting tool or added to an OTF collection, the 0331 Pulsar is designed to be both functional and dependable.
Stainless steel hardware and a stainless steel pocket clip add durability throughout the build while maintaining a clean, cohesive appearance. Measuring 8.125 inches overall with a 4.775-inch handle, the Pulsar offers a substantial grip without becoming unnecessarily bulky. At just 3.75 ounces, it’s light enough for comfortable everyday carry while still delivering the solid feel of a precision-machined aluminum chassis.
Core Edge USA was founded in 2023 by two craftsmen with a goal of creating knives that are unique, functional, and proudly made in America. Based in northeast Arkansas, the company operates two small shops, with one dedicated to heat treating and grinding and the other handling machining, surface grinding, assembly, and shipping.
