We already have a Nut Wizard and ordered another because we get so many black walnuts that fall from our two trees in the fall. I will help my husband pick them up . Excellent product to do the job! Well built!
Nut Wizard contacted me to make sure the extra large was what I needed. I intended to use it for Douglas Fir pinecones which are pretty small. They sent me the large instead and it works well and refunded me the difference.
Not 100%,but gets most my brass and makes the rest easy to find. Only used it 1 time, might get better.
