an improved cutter blade assembly for cutting vegetable products such as potatoes . the cutter blade assembly utilizes a number of cutter blades that transverse an axial bore through which products to be cut are fed . these blades are locked within the assembly by an attachment system that partially deforms the blade to hold the blade in place . this improved attachment connection system serves to hold the blade in a position having higher tension and thereby reduces wear , chatter , and feathering .
