TESTING KNIFE STEELS | spyderco endura 4 vs spyderco sage 1

Spyderco endura 4, in zdp-189 steel vs spyderco sage 1, in s30v steel. I tested these two knives on cardboard and on carpet. Both knives were sharpened to about the same level. If anything the spyderco endura 4 had a slightly more refined edge than a the sage 1 did. Im not sure what happened with the cardboard test. The results are kinda baffling...
