I have bought this film cutter somewhere in the beginnings of 2000’s. It was part of larger Minox lot purchased at the time, and it was a valuable addition to my collection. This item very much looks like it was part of a factory equipment or machinery, but I have no idea where it came from, what sort of equipment was this part of, or who made it, but it cuts through 35mm film negative like hot knife through butter.
The system is based on the well known (and tested) rollers, tensioned in a metallic casing, each roller with two hard plastic washers. You insert your 35mm film leader into the slot, and when it catches onto the rollers, just turn the ribbed button and start cutting. The rollers do a magnificent job, edges are clean, straight and of an exact 9.2mm in width.
One feature that makes this cutter so good (for me, at least) is the fact that the film tunnel (or well) through which the film advances towards the rollers is perfectly made. The film does not wobble inside, which makes the cutting of a straight 9.2mm film very easy and secure.
