Superior blade quality. They hold a cutting edge longer. Teeth enter and push easily through dense wool and fiber. Leaves an even, attractive finish. Our resharpening methods remove less steel than others - so a blade set can be resharpened up to 10 times. Premier blade sets fit Premier clippers 1000c, 3000c and 4000c. Premier blade sets also fit Lister Star, Stablemate and Laser and Neon clippers.
