Diving without a knife is unthinkable for most divers – and for a good reason, too. In an emergency under water, e.g. if a diver gets caught in an old fishing net, being able to cut through the net quickly and effectively is essential for survival. Therefore, many Dive Knives have blades mainly designed for cutting though netting and lines. Of course, these knives are also highly corrosion-resistant. However, proper knife care, especially after use in salt water, is a must. Dive Knives are usually worn in a calf sheath.
