I do wish the list admins would change the default reply-to to be the list rather than the individual. To me that's much more in keeping with the spirit of the list.

A bow saw or other saw with hook or skip teeth rather than chipping teeth might work...where the concave part of the hook is razor sharp to slice rather than chip. 

Yesterday I saw some long sharp landscaping blades which might work, but the people in question (a non-profit maker space) would likely resist spending that much $ on a unitasker. We do have a machine shop but none of those shop captains have a solution. I've seen lots of videos where the roll spins and all manner of things are used to cut it, but we don't have a way to spin it so the saw needs to be the moving part. I may give a fine toothed sawzall a shot and see how badly it tears the weave. There is a cement blade for it, but that's abrasive rather than slicing.
