To use the cutter, first a potato is peeled, then possibly squared on four sides and finally trimmed to a length of 3 to 4 inches depending on the type of cutter to be used. the cutter is a simple hand cutter consisting of a grid of stainless wires or blades, it is placed on the top of the potato and pressed downward cutting through the potato and separating it into square lengths of fries. This type of cutter requires strength to accomplish the downward action of the cutter. It has a handle-operated bin that holds the potato in place as it is manually pressed through a chamber containing the grid of blades that perform the cutting action. Comes with an extra blade for a different size of chips.
