Folding Karambit Knife BOKER PLUS Spike 440A — compact folding blade, ergonomic ring handle

The Folding Karambit Knife BOKER PLUS Spike 440A is a compact folding blade designed for tasks that benefit from a curved cutting edge and precise control. The knife features a curved 440A stainless steel blade and a ring-style handle that supports secure grip and directional control for slicing and close-quarters use. The folding mechanism allows safe storage and convenient pocket carry, making it suitable for everyday carry and utility applications where a compact, controllable blade is required.

Advantages

The curved blade geometry provides efficient slicing and controlled pull-cuts while the 440A stainless steel balances corrosion resistance with ease of maintenance. The ring-style ergonomic handle enhances grip stability and allows for rapid orientation changes and retention under tension. The folding design reduces overall length for safer transport and discreet carry, and the blade lock ensures reliable operation during use.

Suitable for

• Everyday carry tasks that require controlled slicing or cutting in confined spaces
• Utility tasks such as opening packages, cutting cordage, or trimming materials
• Outdoor activities where a compact, easily retained blade is preferred
• Situations requiring quick blade orientation and secure retention

How to use

Open the folding karambit carefully using the designated deployment feature until the blade locks in the open position. Hold the ring-style handle with the index or middle finger through the ring and the remaining fingers along the handle to maintain secure control. Use the curved edge for controlled pull-cuts or slicing motions; apply steady, even pressure and let the blade geometry guide the cut. After use, ensure the blade is clean and dry, unlock the folding mechanism and fold the blade back into the handle for safe storage and transport.

Usage recommendations

For longevity, clean and dry the blade after exposure to moisture or abrasive materials and periodically check the locking mechanism and pivot for dirt or wear. Use appropriate cutting techniques for curved blades—draw cuts and slicing motions are more effective than straight stabbing techniques—and always follow local laws and safety guidelines regarding carry and use of folding knives.
