Cutting 8x10 film without scratches

[DolphinDan]

I have a custom 6x7 (inches, not cm) back and film holders which I enjoy shooting landscapes with. I cut down 8x10 sheets of film to 6x7 and 4x5 sheets using a ROTATRIM RC RCM12 12 inch cutter. However, when I see the developed sheets of film I notice slight/tiny scratches on the film. And when scanning the film, these scratches come up as unpleasant bright blue lines. I checked the film holders and other possible sources of scratches, including using a different photo lab, and the problem seems to be the Rotatrim cutter. I would appreciate any advice on how to cut 8x10 sheets of film down to 6x7 and 4x5 without scratching them.

Fold it over and lick the edge, then put if over the edge of a table and pull down, it will cut it beautifully.

Just joking.

Try putting a sheet of paper on top of the paper cutter and under the film before you cut it. I make the cuts with emulsion side up.

Thank Keith.

I will give it a try.
