Understanding the Cold Steel Kobun Fixed Blade Knives

The Cold Steel Kobun is a lightweight, ultra-thin boot knife designed for discreet carry without sacrificing the reach of a 5.5-inch blade. Its western-style tanto geometry and textured Kray-Ex handle make it a highly effective tool for both tactical applications and utility tasks.

What steel is used in the Cold Steel Kobun series?
Most models in the series use AUS-8 stainless steel, a reliable material known for its toughness and ease of maintenance in the field. Some premium variants, such as the Lynn Thompson Signature edition, upgrade the blade material to high-performance S35VN steel for enhanced edge retention.
What are the blade characteristics of the Kobun?
The Cold Steel Kobun features a 5.5-inch western-style tanto blade with a hollow-ground main edge and a flat-ground tip for reinforced strength. This series is intentionally thin, with a blade thickness of just over 3/32 of an inch, allowing for an incredibly slim profile that excels at slicing.
How is the Cold Steel Kobun intended to be carried?
The Kobun is designed primarily as a boot knife, though its slim profile also makes it an excellent choice for inside-the-waistband (IWB) carry. Each knife includes a Secure-Ex sheath that can be further customized with large or small Tech-Locks if you prefer a standard belt carry configuration.
What handle material is used on these fixed blades?
The series utilizes rubberized Kray-Ex handles which provide a secure, non-slip grip even when wet. These handles are textured and slightly contoured to ensure the knife remains comfortable and controllable during use despite the very thin overall profile of the tanto blade knives in this lineup.
How much does the Cold Steel Kobun weigh?
The Cold Steel Kobun is remarkably lightweight for its size, weighing in at approximately 4.1 ounces. This makes it an ideal choice for users who need a full-sized fixed blade that can be carried all day without feeling bulky or restrictive.
What color options are available for the Kobun series?
The series offers a variety of colorways, including handle options in OD Green, Desert Tan, and Earth Brown, alongside the traditional black. Depending on the specific model, these handles are paired with either a classic satin finish or a black-coated blade.
