I have a few saw blades that need sharpened and I was wondering if it would be better to pay the $10 a blade (25 cents a tooth) cost or purchase a dedicated machine. LIKE THIS In addition I also have some planer blades that need sharpened. What is the best way to go about this? I have a local reputable shop that can do the job. I am wondering if I will be better off just doing it myself since it is a bit of a hassel to drop off and pick up the blades.
