This buttercut dog clipper blade is made of premium-quality, high-carbon German steel to cut precisely and cleanly for superior results. Rockwell hardness is 70, edges stay ultra-sharp longer. Compatible with all type A5 detachable blade clippers. Blade sets should be oiled once a day minimum. Ideally, it should be done before every grooming. After oiling, be sure to use a soft, dry cloth to wipe any oil off the external surfaces. Oiling Blades - Place a few drops of blade oil on the front and side of the cutter blades. Wipe excess oil off blades with a soft, dry cloth. Spray lubricants contain insufficient oil for good lubrication, but are an excellent clipper blade coolant. Cleaning Blades - Immerse blades only while clipper is running in a shallow pan of clipper oil or blade cleaner. After cleaning, turn the clipper off and dry blades with a clean, dry cloth. If blades will still not cut, there may still be some hair trapped between the upper and lower blade. Remove the blade off the clipper and slide the upper blade to one side without loosening the tension spring or moving the upper blade completely out from under the tension spring. Wipe the surfaces of the blades clean with a dry cloth, then place a drop of clipper oil where the upper and lower blades meet and also in the guide slot of the tension spring.
