I've been using a Personna blue/lab this week. It's a nice blade: pretty sharp and pretty smooth, with good longevity. I usually stop after 12 passes but I think I'll go a bit longer with this blade.
Since I just got my Rockwell T2 stainless it came with five Rockwell blades probably made in china but so far so good on day four on the first blade I might buy a few after I use the five that came with it.
