The title pretty much sums it up. I'm shooting a few non-standard formats for which film is hard or impossible to get. To get to the right sizes for the emulsions I want (provia, velvia, foma, fp4), I'm cutting 8x10 sheets. I do this on my rotatrim with small blocks attached to the sides to easily get the right alignment of the sheet in the dark. In itself this process works fine. I've never scratched a sheet and only once made a cut that was not straight. Perfectly acceptable considering the number of sheets I've cut this way. However, the catch is that this takes a long time! Is there anyone with experience in cutting film who has a quicker solution? Not at the cost of consistency, particularly fuji slide film is very pricey per sheet and I rather spend a bit more time than ruin my film.
