Marine steak knife
These Swiss hand-made folding steak knives are made of surgical steel, which has four times more corrosion resistance than the standard grades used for cutlery. Handles are crafted from stabilised walnut or ash, chosen to avoid swelling when wet. Ceramic bearings ensure the blades are easy to open, even after prolonged exposure to wet and salty environments.
Price: from CHF 239 (approx £189). www.sknife.com
