I'm leaning toward not, the one I have doesn't look buffed, at least not recently and it seems to have a similar disposition. I looked at it again since I shaved with it last and there appears to be some issues near the toe, although I think the kids made off with my higher powered loupe, so I'm basing this off of 10x magnification. I'm going to keep an eye on it. If I get bored I may try to hone/grind a little further up into the meat of the blade and see what happens.
Not sure what you mean by issues near the toe. I have seen numerous old Sheffields hold an edge except for the last few mm near the toe. So far the adage to stay on your 1k until the entire length holds an edge seems to be true.
My theory is that the geometry of the blade is such that the bevel angle at the toe is less and not sufficient to hold a strong edge. But I have yet to prove this theory.
