I have at least three blades that I have bought new which simply don't go through the coat: 3, 7 & 5. I use an Oster A5 Dual Speed clipper and the blades are Oster. Problem is I bought them at Discover Dogs and can't remember the seller.
I now have 4 SP's and although not great at grooming I do bath and clip them every 5-6 weeks. I have tried aligning them by using the screws, oiling them etc but nothing seems to work. I am loathed to send them off for sharpening/repair as effectively they have never been used. Any suggestions as to how I can get them to work?
