Boker Heckler&Koch OTF SP02 Spring Knife

A spring-assisted OTF (Out The Front) knife featuring a blade that deploys forward when the loaded spring is activated. The 82 mm blade is crafted from D2 tool steel, while the handle is constructed from textured aluminum finished with a black coating. A sturdy clip ensures reliable everyday carry.

Dagger-profile blade, D2 tool steel

Featuring a dagger-style blade with a pronounced deep concave grind, this knife is crafted from D2 tool steel hardened to 58–59 HRC. The steel offers exceptional abrasion resistance along with reliable protection against corrosion.

Automatic opening

A knurled slider integrated into the handle enables blade deployment. Shifting the slider downward tensions the spring and withdraws the blade.

Aluminum grip, springy clip

The handle is crafted from aluminum, offering both lightweight performance and resistance to corrosion. A non-slip texture with the Heckler&Koch logo ensures a reliable grip, enhancing knife control in a variety of environments. For convenient everyday carry, a springy, reversible clip on the handle enables secure attachment to a belt or pocket. A robust glass breaker is integrated at the end of the handle.

NOTE

Despite widespread "urban myths," spring-loaded knives are fully legal to buy, possess, and carry in Poland. The law imposes no restrictions on opening mechanisms, blade shape, or blade length. However, other countries may enforce laws restricting or banning certain knife types—prior to traveling internationally with a knife, ensure you are aware of and comply with local regulations.

D2 feature
D2
D2 is a high-carbon tool steel classified as semi-stainless, characterized by high wear resistance and the ability to maintain a thin, durable edge. It achieves a hardness of 57-62 HRC, which ensures long-lasting sharpness even with intensive use. Its chemical composition is a precisely selected combination of elements: carbon (1.4-1.6%), chromium (11-13%), molybdenum (up to 0.8%), vanadium (up to 1%), manganese (up to 1%), and silicon (up to 1%). The high carbon and chromium content ensures hardness and wear resistance, while molybdenum and vanadium improve the strength and durability of the cutting edge. Although D2 steel is not completely stainless, its corrosion resistance is sufficient to meet the requirements of most conditions of use. It is widely used in the production of mid-range and high-end knives, including handmade knives and cutting tools.
