We've been test cutting on various fabric and it'll be added to this thread.
Using Longship Armoury 5160H Ex-blunt Dadao, micro beveled battle sharp edge to test cut a shin difficulty newspapers rolls with twin bamboo strips core, covered with linen bag.
Using a cold steel o katana on 0.8mm PU fabric covered newspapers roll with twin bamboo strips.
Dung used his cold steel grosse messer cutting the 0.8mm PU fabric covered target. The subtitle in the video was wrong about 8mm thickness. I missed the "0." part in typing.

You are now in a subject that greatly attracts my attention. Unfortunately some material designations used in Hong Kong I am not familiar with, such as PU. Is PU aka polytetrafluoroethylene, aka Gore-Tex? It is good that you included the thickness although it was in millimetres. Most fabrics that I am familiar with are measured in ounces or denier. Linen comes in various weights. I am familiar with 10 and 14 oz. My pet peeve is someone saying that “I used denim”. What weight, new or used? For what it’s worth, I’ve found that a knitted stretchable material is harder to cut through than a non-stretchable cloth such as broadcloth.

PU is polyurethane fabric, one kind of synthetic leathers. I agree with you definitely. The elasticity of the fabric equals to its ability to wrap around the edge, increasing contact surface thus lowering pressure in contact, thus avoiding being cut. This is one of the students trying to cut with a fabric covered newspapers roll, with twin chopsticks core. Dunno what cloth she used.
