I've used a ton of S30V blades from different producers now and I also have a new Chris Reeve Sebbie in S35VN as my EDC. I have noticed with this S35VN @ 58-59 RC that it takes a slightly better edge than S30V, though it seems a bit softer. Edge retention seems to be close...but a little less than S30V...but it is definitely easier to touch up and get back to hair popping sharpness. At the end of the day, I see it as a slightly better blade steel. This, however, depends on the user.
