An apparatus for accurately cutting baitfish at a compound miter angle of forty five degrees. The apparatus automatically centers the bait fish within a transverse well at the bottom of a half pipe tube capable of accommodating various common bait fish sizes. The compound miter cut provided by this apparatus exactly matches the compound miter found within the construction of the Sure Spin Herring Helmet® Angler Innovations. The present apparatus is easily washable and leaves no trace of fish scent between uses as it is constructed from non-absorbing high density polyethylene (HPDE). The apparatus further provides safe usage as downward pressure is applied to the cutting tool and bait fish as the cutting tool blade enters the blade slot groove. The present apparatus is constructed with two half pipe options to accommodate multiple bait fish dimensions.
