Magnetic knife rail - holds even the
heaviest knives.

This is how professional chefs store their knives - within sight and easy reach. Two strong parallel magnets are fitted into the aluminium section, so that even large kitchen knives and scissors can be held safely.
The advantage over a knife block is that the knife length and blade are always visible.
This rail is extremely practical in workshops as well as kitchens. It saves room and helps to keep work surfaces clear.
