La Gloria Cubana did, maybe still does, these cigar rolling events at B&M locations were they would bring Leo Peraza, master roller to assist and teach customers how to apply wrappers. They brought these 5 inch solid rotary blades that were mounted in an over head handle that looked like these except they had solid blades. They had a La Gloria Cubana insignia on them that you would see on the box top or, cigar band.
I do have a tiny rotary blade I'll use sometimes. but, it does disassemble so.. . Can't beat a chaveta for sure.
They most likely want you to buy a case of them so that when they get to smelling to bad, you can just throw it out and grad another.
Maybe for tobacco, not food. But, it's to big.
