I guessed high hoping I was wrong. I've got a couple custom hunters with 4-1/2" or so blades in 154CM and I have always been very happy with them. I don't split or chop bone with them except on maybe rabbits or squirrels (that's been a while ago) and of course fish. Pardon the cut-n-paste but here is some steel info.

154CM/ATS-34 is a high carbon stainless steel generally regarded as a direct upgrade to 440C. It has a high wear resistance for a stainless steel and a low edge stability both due to the large carbide fraction with primary carbides as large as 25 microns. It is one of the more brittle stainless steels and in general works best on smaller blades intended for extended aggressive slicing.

440C has an increased hardness and carbide fraction than 440B and thus offers a higher wear resistance but lower edge stability. 440C can be considered to be a high wear upgrade to 12C27 where a high edge stability isn't desired. However for this purpose, other alloys are generally regarded as superior such as 154CM. Dendritic 440C is focused on extended slicing aggression and as very brittle due to the retained as cast carbides.
