Ka-Bar Becker Harpoon BK18 Fixed Blade Knife - Black

Survival knife from the Becker Knives series with a Full Tang construction and a Harpoon profile blade made of 1095 Cro-Van high carbon steel. The black handle is made from Ultramid polymer, and the knife was designed by Ethan Becker. The set includes a Celcon polymer sheath for safe carrying.

1095 Cro-Van tool steel

The blade is made from 1095 Cro-Van high carbon tool steel, hardened to a hardness of 56–58 HRC. The steel offers high resistance to chipping, making it ideal for demanding outdoor tasks. The addition of chromium and vanadium increases hardenability, boosts edge stability and wear resistance, and keeps the steel easy to resharpen.

Harpoon profile blade with a matte finish

The Harpoon profile blade with a thickness of 4.5 mm is coated with a black matte protective finish to enhance corrosion resistance and reduce light reflections. The plain cutting edge ensures precise cutting, and the robust build is suited for tough field tasks. Jimping on the back allows a secure thumb rest, improving safety and precision during field use.

Ultramid polymer handle scales

The handle consists of contoured Ultramid polymer scales, made from tough structural polyamide that resists impact, abrasion, and harsh outdoor conditions. This material provides a rigid, stable grip, and ergonomic shaping improves control during intensive use. The handle features a glass breaker at the end and a lanyard hole for attaching a safety cord.

Celcon polymer sheath

The sheath is made from Celcon polymer, which is abrasion-resistant, moisture-resistant, and stands up to extreme temperatures. The knife is secured in the sheath by friction and an additional strap with a steel snap to prevent it from falling out. The design allows you to switch the sheath to either side for belt carry.

Militaria.pl is a premium dealer of Ka-Bar.


Ka-Bar is a brand whose history dates back to the late 19th century, and which gained real fame during World War II, when the Fighting Utility model was officially adopted by the US Marine Corps. The durable and versatile knife quickly became legendary, proving itself both in combat and in the daily tasks of soldiers. The name Ka-Bar itself comes from the 1920s, when a trapper described in a letter how he managed to “kill a bear” with a Union Cutlery knife. In 1952, wanting to emphasize the power of this symbol, the company officially changed its name to Ka-Bar Knives Inc., and its products are still considered a model of reliability today. An important chapter in the brand's history is also its collaboration with Ethan Becker, which resulted in the Becker series, highly valued by users, combining practical solutions with a modern approach to knife design.

1095 Cro-Van feature
1095 Cro-Van
1095 Cro-Van steel is an improved version of classic 1095 steel, with increased wear resistance and improved edge durability. Its carbon content of 0.95-1.1% gives it high hardness (58-60 HRC), making it ideal for the production of survival, tactical, and outdoor knives. The steel also contains chromium (0.4-0.6%), molybdenum (up to 0.06%), vanadium (0.15-0.25%), manganese (0.3-0.5%), and silicon (0.15-0.25%), which contribute to its abrasion resistance and improved edge stability. Although it has low corrosion resistance, it requires proper maintenance in humid environments. Thanks to its optimal combination of hardness, blade durability, and moderate corrosion resistance, it is a popular choice among enthusiasts of knives for intensive use.
Ultramid feature
Ultramid
Knives with handles made of Ultramid are lightweight, highly durable, and dimensionally stable even under intensive use. This polyamide from BASF is resistant to impact, abrasion, chemicals, and temperature fluctuations. Available in versions modified with glass fiber, carbon fiber, or mineral additives, it provides even greater rigidity and heat resistance. Thanks to its injection molding and machining capabilities, it allows for the precise manufacture of handles with a secure grip, durable fastening of metal elements, and an aesthetic finish.
