Review on Warner Utility Molding Replacement 10100 by Anthony Mayes

What have you done, Warner? I bought this exact set 6 years ago and now only needed to change the blades but no spares are sold just the original set. I went with it anyway since the first set worked so well. BAD CHOOSE. Each blade was blunting and chewing through my project within minutes of starting! It was all work on ONE project and I could see the neat work of the old blades alongside the destruction of the new blades. Hours of work destroyed by a totally inferior tool. Why? What did you change to cut costs and fool your customers?
