This invention relates to a cutter rotatable the arms 18 and I9 are provided with kerfs or with a shaft which carries it and used ordinarily grooves 20 and 2|. These grooves are arranged for cutting meat into small particles for use as at an angle to'the plane of that side of the knife hamburg steak, and the like. carrier and bothsets of'them at the same angle,

The. principal objects of this invention are to which may be approximately 20. That is, they provide such a rotary cutter with a series of 1 slant in the direction in which the cutter is to blades fixedly but detachably secured and adjustrotate. At the back of each groove is a short able; to provide each blade with an integral pordepression 22 which can be a continuation of the tion constituting another blade so that if there groove 2| but is used'for removal of the knives, '1 are four of the first named blades, there will be as will appear hereinafter.
