The Airwolf Oil Filter Cutter has been hailed as the “best filter cutter we’ve ever used” by AOPA Pilot, and with good reason -- it’s unique design makes it a snap to cut through any type of oil filter. It’s also currently the only oil filter cutter available that will cut through the new-style Champion filters with the thicker casing. The Airwolf is machined from solid 6061-T6 Aircraft-Grade Aluminum and fitted with stainless steel rollers for smooth cutting. The high carbon steel cutting blade is hardened to 60 Rockwell and honed to razor sharpness to produce clean, consistent cuts. Every mechanic knows that an oil filter cutter is an essential tool; and if you demand the best, then the Airwolf is for you. 2 lbs (1Kg) shipping weight.
