BRAND NEW - SEALED Oster Cryogen-X AgION Blades with Built-In Antimicrobial Protection For All Oster Turbo Golden A5 Size 7F - 1/8" cut/3.2mm. Blades Are Scratch and Rust-Resistant Made in USA Compatible with Oster, Andis, Conair, Wahl, and Laube detachable clippers. Catalog Part Number: 078919-166-003 Cryogen-X AgION Blades have advanced, silver-based AgION antimicrobial protection built in to prevent the growth of bacteria, mold, and mildew on blade surfaces. The importance of regularly cleaning animal grooming equipment is often overlooked. Blades that are covered in hair and animal dander are ideal breeding grounds for microbes. Contamination of the blades can result in a more rapid disintegration of the metal, and regular cleanings are often time consuming and can be costly, and do not always adequately clean the irregular surfaces and crevices of the blades. The AgION compound provides protection against microbes by releasing silver ions to the surface at a slow and steady rate. This creates a self-cleaning surface that provides safe, continuous, long-term protection from bacteria, fungus and mold. Large numbers on blades make identification easier. Compatible with Oster, Andis, Conair, Laube and Wahl detachable clippers. Oster uses cryogenic technology to create the hardest blades ever. Cryogenic processing conditions metal to 300 degrees below zero, so molecules are aligned in a perfect structure. The result is a harder, denser metal that holds a sharper edge through prolonged usage. A5 Cryogen-X Blades also withstand more sharpening treatments for unsurpassed longevity. Sharper blades glide through coats with less effort, saving you and your clipper from unnecessary fatigue and wear. Cryogen-X Blades are manufactured from fine-grain, high-carbon steel that is cryogenically treated. With a Rockwell Hardness rating of 62, these durable blades were designed with the busy groomer in mind. Blades stay ultra cool for optimum durability. Powered by Turbo Lister
