Camping once with a buddy. I was batoning and chopping with my 911. She took a licking and asked for more. I then started doing the same with my buddy's sarge 7. The infi accumulated very small yet visible rolls in the blade. Both edges were factory edges. That is my only experience with infi. I am just learning to sharpen blades by hand and I find that Sr 101 isnt difficult, just more time consuming than some other metals. Price to performance, I would take Sr 101 any day.
