These Timberwolf blades are the best blades I have ever used. I primarily cut green wood for bowl blanks and these blades cut very quickly with little resistance. The cutting edge lasts a long time, but after hitting a stuck stone or metal, it's quick to sharpen at home. I use a dremel wheel and it takes about 10 minutes to resharpen a 105 inch blade. I have tried many cheaper blades but none compare to Timberwold.
