Famoré Cutlery's new rotary handle is designed with the same quality and affordability you've come to expect from us. The 400RT comes with ONE of our 400SKS blades and a special screw needed to use with our 400TC blades. The handle fits our blades as well as any other standard 45mm rotary blade on the market. What makes the Famoré rotary handle different from other handles currently available? Our handle's screw/nut mechanism has been designed with ball bearings to cut down on friction and hand fatigue, i.e. you don't have to press so hard to have it glide through multiple layers of fabric!
