I discovered a great tool for splitting turkey wing feathers this year. While visiting our daughter and her family in Alaska I bought an ulu. It is a curved single bevel blade with the handle on top used by native Alaskans for skinning and cutting. It works great on the turkey quills. Just set the blade in the quill groove and roll it along the groove. I joined the Wild Turkey Federation here in Northeast Michigan and many of the local hunters here are more than willing to let me have their wings. I wound up with approx. 15 sets of wings this year. One other thing, the single bevel on the ulu lets you practice sharpening single bevel blades.
