I've been reading about the two steels mentioned in the subject. In my short experience with Aus 8 has been very good with boker knives. What about spyderco 8Cr13Mov? Is it a better material than boker aus 8?
Question for 8cr13mov straight edge (no serrations).
How well does it hold an edge compared to aus8? For example: 45 slices full length of blade through cardboard.
Does the 8cr13mov rust?
Is it chemicals resistant?...example: 100 lemons sliced 1 way cuts.
 
This isn't really a Shop talk question.

8cr13mov is very similar to AUS8 in edge rention and ease of sharpening. Neither one will hold an edge as long as say S30V or VG-10, but they are really easy to sharpen. 8cr13mov is a chinese steel. It's a fairly good stainless, although not as good as say H1. I've never seen any 'Lemon' tests on it though.
 
Yeah I would say anecdotally that they are too close to call. I doubt you could tell the difference between the two.

Also, I really like CS's AUS8 better than the rest

This. You won't notice any difference based on the steel itself. Any difference you notice will almost certainly be due to different blade geometries.
 
I've used several 8Cr13MoV and AUS-8 bladed knives, but very limited experience specifically with Spyderco's and Boker's models with those steels. In general, I've found edge retention to be pretty comparable between the two. Both are pretty easy to sharpen, although the AUS-8 blades seem to take a finer edge (purely subjective, based on my test cuts through paper/newsprint after sharpening and looking for frayed edges along the cut or snags/tears). Rust isn't a big issue for me (I'm pretty far inland in hot, relatively dry climates), so I can't really compare the corrosion resistance.

Overall, both are good EDC blade steels and offer very good value. It is usually a pretty big step up cost-wise to get some higher-end steels, and even then, the cost to performance ratio does not improve linearly.

I got my resilience today. After sharpening the 13mov blade and aus8 on my boker kalashnikov 74. I sliced 5 medium priority boxes in 7×5 slices. Blades held up great minus some sticky tape left i think the spyderco held an edge better than the boker.
