I used Arkansas stones for 15 years until I wore out my first one. The ones after that just didnt seem the same. I always used them oiled. The drawback I found is that they dont cut the new alloys very quickly. On 425 Modified (Buck) and Sandvick 12C27 (Benchmade balisong) and plain carbon steels (10xx alloys, usually 1095) they work well. 440C and up takes some time.
I've never had any problem using Arkansas stones on 440C
No, you shouldnt have to upgrade just for one blade with 440C. I used my Arkansas stones on a 440C kitchen paring knife for a couple of years with success. The exception would be if you need to remove enough steel to repair chips, fix impact on concrete or rocks, or reshape a broken tip. I am of the opinion that the newer Arkansas stones, say in the last 10 years, are not as good as the old ones. If you have older ones, or managed to find a good one, it will work on 440C fine. There are so many other variables to take into account that stone type is not a deal breaker for sharpening 440C, or even 154CM and ATS-34. It just may take a little longer.
