We charge $5 per blade. Please take care in packaging your blades prior to shipping so that the prongs are protected. If you cannot drop kick them and be confident, then they're not protected. Also send with a return label or how you would like to pay for return shipping. Please use our Contact page when sending your blades. So we know to be looking for them and how many to expect. We are only sharpening clipper blades at this time.
