Normal “marine grade” stainless steel, in terms of diving knives, is generally the name given to 420 grade stainless steel, also known as “cutlery grade”. While it has a good corrosion capacity in water, it does not have such a good capacity to hold a sharp edge. Titanium can not create as sharp an edge as stainless steel. The grade of stainless steel used in the EEZYCUT 360 ˚ anzeigen (440a) is known for its capacity to hold an extremely sharp edge, while having very good corrosive qualities. When the blade loses its edge or starts to corrode, you can easily put a new blade in, and yet again have the sharpest, cleanest cut in the water. Washing in fresh water after diving is recommended for all stainless steel knives and blades. All stainless steel which is used in salt water needs to be treated with care. Carefully coating any stainless steel blade in normal divers silicone grease prior to salt water usage significantly prolongs the life of the blade.
EEZYCUT only recommend EEZYCUT blades. Most carpet blades are thicker, and do not fit the 360 ˚ anzeigen.
