The KA-BAR Mark 1 USN (2221) is a faithful reproduction of the classic U.S. Navy utility knife issued during WWII. In fact, this design was so effective that it became the basis for the later, more famous KA-BAR fighting knives. Consequently, this model honors that specific history with the “USN” tang stamp and a non-reflective black blade.
This knife is built for uncompromising utility, making it an ideal choice for outdoor adventures, bushcraft, hunting, and general field tasks. First and foremost, it wields a versatile 5.125-inch straight-edge blade forged from 1095 Cro-Van steel. Specifically, this is a high-carbon alloy favored for its exceptional toughness and ease of sharpening. Furthermore, the blade is protected by a black powder coat for added corrosion resistance.
Moving to the handle, it maintains its classic, time-tested design. For example, it utilizes stacked leather washers, which are compressed and shaped to provide a secure and comfortable grip in all conditions. As a result, this construction is securely finished with a powdered metal guard and butt cap, ensuring the knife is perfectly balanced and robust.
This specific model, the 2221, comes with a classic brown leather sheath embossed with the “USN” emblem. However, for those who prefer this same Mark 1 design with a plain tang stamp, the KA-BAR 2225 is an excellent alternative.
Regardless of which you choose, when you aren’t carrying this piece of history, it deserves to be protected and displayed in the Tomar’s 1431-SAB presentation display case.
Proudly made in the USA, this knife is a legacy. Therefore, for more information on their full lineup, you can visit the official KA-BAR website. Ultimately, the KA-BAR Mark 1 USN is a perfect blend of history and practical utility.
