straw chopper knives

A sharp product
A straw chopper knife is exposed to particularly high wear at the outer edges of the blade. In this area, the sharp cutting edges are subject to the greatest wear and tend to round off. With hard cover knives, one side of the blade is harder than the other (beaver tooth effect). This means that a sharp edge remains where the soft material is worn away.
