This is a new model of this classic item, now made by us with custom made penknives, in anodized aluminum, which will never rust. The penknives appear normal in all respects, and you can open and close the blades, as in any penknife. However they are not designed to cut, or sharpen pencils.
They are designed as a rust free closeup magic prop. Supplied complete with routine.
