Oster® Professional blades are produced from the finest high-carbon steel and handcrafted to our rigorous standards, providing unparalleled precision and performance. Furthermore, our U.S. made blades are hardened to RC62-66 (Rockwell Scale C) in-house prior to receiving a cryogenic treatment which further enhances the hardening process. The blade cutting surfaces are then sharpened, finished and tested with proven Oster® proprietary processes, ensuring ultra-sharp blades that continue to stand the test of time.
Oster Blades come in a variety of lengths, each with a different number so that different coat lengths and styles can be created. So it also worthwhile checking that the blade you are purchasing is compatible with the brand of clipper you intend to purchase. Clippers blades are also made for a variety of purposes such as show edge, ultra edge and manufactured with different metals and coatings such as stainless steel, ceramic, with carbon and titanium coatings.
Fine tooth blades give a finer finished look to the coat. These are best used on a fine and soft coat, for example any of the small fluffy breeds. The final clip will be very even looking and very smooth. Fine tooth blades are distinguished by the letter ‘F’ after the number, for example 4F, 7F, 3F. These blades will work beautifully for dogs whose coats are regularly clipped and/or brushed however they will not work on a dog who is matted or very thick undercoat near the skin. This is because the coat is just too thick for the blade to cut through.
A skip tooth blade helps feed the hair into the cutting blade more effectively plus it is good for a rough cut prior to washing the dog. It can certainly be used for the finished cut – it just leaves the dog’s coat with a more layered look but it still looks neat and tidy. It will probably be necessary to use a short skip tooth blade on a dog who is matted or very thick close to the skin.
Dog clipper blades are generally made from either stainless steel or a ceramic material, and incorporate elements of either titanium, silver, carbon or chrome into the mix or as a finish. Carbon-infused steel offers a harder cutting surface and claims to stay sharper for longer; chrome finishing offers more rust resistance while Oster Cryogen blades use silver, because of its antimicrobial properties, as the active ingredient to help control the growth of bacteria, mould and mildew (this is extra protection in the professional groomer setting where dogs are being clipped quite close to each other). Ice-tempering is performed on some blades to assist with rust-prevention as well as helping to keep them cooler for longer while in use as they do tend to get very hot during use.
