I have a a Forest WW II 40 tooth on a Powermatic 66 since 1990. It has been sharpened 3 times a great blade in my IMO. I also have the Forrest Dado set. None compare to it, but than again it was almost 300 dollars 20 years. ago. Have both Forrest chopaws blades on a 10 and 12 inch saw and a 12 inch blade on a DeWalt 7790 RAS. I love all of them. Freud makes an excellent product but if I could only pick one blade it would be a Forrest. My friend who is a professional woodworker in Vail, Colorado used to use Freud blades until I turned him on to Forrest. He now has the Forrest blades on of of his eqiupment including a $40,000- Altendorf and $20,000 Martin sliding table saw. He claims in his view there is no comparison.
