The bevel was set and it had a good edge, prior to using it (40 shaves ago). Started getting some irritation with it, so I moved to the next blade in the rotation. It has a small secondary bevel on it.
I'll give a shot with the 4K, and see how it goes. If I don't make progress, I can try the 1k (I do have a 2k SS as well (forgot about that one). As RezDog highlighted, it is very shallow, less than 1/4mm.
Will give it a go tomorrow night (hopefully).
Thanks for the suggestions/recommendation everyone.
