I would recommend a fixture specifically designed to sharpen tools using a surface grinder. If you have the proper tools its easy. If not then I would send them out to be sharpened. A company setup for this will yield much better results. If you do not sharpen them properly you will shorten the life considerably and thus defeating the purpose for sharpening them yourself.
Any good tool supply company will have the fixtures and the wheels for the application. your local phone book will have tool sharpening companies.
Good Luck!!
