The French Fry slicer (Harbor Freight #93001) works like a charm. It comes in its original box with the manual. The slicer has a suction cup base and makes 1/2 inch fries. It was used once and has been cleaned. The Hassleback cutter is in perfect condition also having been used once. It is unboxed with no manual but recipes for this yummy potato can be found online. The Hassleback cutter is used to make partial cuts halfway or more into the potato and then the cuts are stuffed with things like cheese.
