The two things I always use to test any sort of edges are adding machine or receipt paper (without bias) and manila rope.
They are both abundant and almost free.
I've also used a lot of waistbands from old clothes for coarse edges and Charmin extra strong TP for refined edges.
Examining the cuts in paper under magnification will yield more detailed information of the edge, especially of tooth (micro serration) and burr.
