Spearfishing Knife: It features a thin, extremely sharp tip for easy penetration. It is the top choice for spearfishing, ensuring the immediate killing of the catch. It is not recommended as a safety knife due to the risk of puncturing equipment
Urchin Cutter : Specialized tool with a sturdy construction, designed exclusively for opening sea urchins and shellfish. It does not have a traditional cutting edge, so it does not replace a diving knife, nor does it function as a safety tool for cutting ropes
Collapsible: Compact and practical, it folds like a pocket knife for safe storage in the BCD pocket. Ideal as a backup tool. It is not recommended as the main rescue knife, as it takes time and usually two hands to open
Fixed Blade: The most reliable choice for a primary safety tool. The blade does not fold, offering maximum durability and immediate one-handed use, even with thick gloves.
Flexible Hose: Attaches to the BCD inflator hose. Ideal choice for small knives or cutters. Ensures immediate one-handed access to the tool, right at chest level, for maximum safety.
Mini: Up to 9 cm in length. They are lightweight, small, and intended exclusively for the vest (BCD), the hose, or the arm.
Medium: With a blade length from 9 to 13 centimeters. The most popular category. These are classic general-purpose knives that are usually worn on the leg or belt.
Large: With a blade length of 13 centimeters and above. Heavy-duty knives (machete style), usually for professional divers, technical diving, or specialized spearfishing.
Stainless Steel: It offers high resistance to oxidation from saltwater and retains its edge. It is the most classic and reliable choice for divers, provided it is thoroughly rinsed with fresh water after every dive to prevent rust
Titanium: The top choice. Titanium offers 100% immunity to rust in saltwater, even without thorough rinsing. It is extremely lightweight, non-magnetic (safe near compasses), and retains its edge for years
