Boker Plus Micro USB OTF Spring Knife - Blue
OTF spring knife (Out The Front), in which the blade extends from the front of the handle when the tensioned spring is released. The blade with a Clip-Point profile is made of D2 steel, which is characterized by high wear resistance. The aluminum handle in Blue is styled like a USB flash drive.
Tool steel D2
The knife blade is made of tool steel D2, which is characterized by high cutting aggressiveness and significant abrasion resistance. After hardening, it reaches a hardness range of 57–62 HRC, which translates to long-lasting sharpness even with intensive use. D2 steel is not fully stainless, but its corrosion resistance is sufficient for everyday use.
Clip Point profile blade, satin finish
The smooth blade with a Clip-Point profile has a length of 40 mm and thickness of 2.3 mm. It is ground with a flat grind, which ensures effective cutting and precise task execution. The blade's satin finish provides a semi-matte surface, enhances aesthetics, and increases resistance to scratches that occur during use.
Aluminum handle, metal clip
The handle styled like a USB flash drive is made of anodized aluminum with a delicate texture obtained through milling, improving grip security. The knife is equipped with a tip-down type clip. At the end of the handle, there is a hole for threading a cord or lanyard.
OTF mechanism
To extend the blade, simply push the slider on the handle forward, which releases the tensioned spring and dynamically extends the blade from the front of the knife. The mechanism operates smoothly and allows one-handed operation, increasing convenience for everyday use. Sliding the slider in the opposite direction tensions the spring and retracts the blade back into the handle, simultaneously securing the knife in the closed position.
note!
Polish law does not impose any restrictions on knife opening mechanisms. In other countries, regulations may exist restricting or prohibiting the carrying of specific types of knives - if you are traveling abroad with a knife, it is worth becoming familiar with them.

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.
Satin
Satin finishing is one of the most popular blade finishes, achieved by grinding the steel with fine-grained abrasives. Parallel micro-scratches remain on the surface, giving the knife a technical, matte appearance. Satin finishing has both aesthetic and practical significance - a smoothed blade is easier to clean, and the slightly reduced friction promotes smoother cutting. Depending on the direction and intensity of polishing, different effects are achieved - from a matte finish to an almost mirror-like finish. Satin is valued in both utility and collector's knives because it emphasizes the structure and quality of the steel while maintaining functionality.

A very pleasant little clicker. The mechanism is very satisfying, allowing for many hours of satisfying ADHD and fun. It doesn't attract strange looks from bystanders. I recommend it.
