154CM and ATS-34 are very similar. Here's some more info. Personally, I've never used ATS-34. I've found 154CM (on various Benchmades and Leathermans) to be quite good. My only KAI knife with 154CM is the 0200. The CPM-154 in the CF Blur is the same chemical composition as 154CM, but made using the powder metallurgy process. It's performed quite admirably on my FrankenBlur so far (have only had it a couple of months).
