What is the best tool or machine to use. What angle degree for upper and lower blade and do I use same angle degree for both or should they be different?How much hand pressure do I use when sharpening. How many times on average can a pair of grooming shears be sharpened?

I don't know anything about actually sharpening the shears, but I know that you can get it done by sending them in. The website for Ryan's Pet Supplies, a wholesale supply company (with tons of awesome products like clippers, shears, shampoo, etc) and you can send in your clipper blades, shears, and other stuff to be fixed up, sharpened, and refurbished. We have a guy that sharpens everyone's blades where I work, but he's just kind of a local guy that does it part-time. He's very good, though :mrgreen:
