I found this on my last purchase, I ordered a pro blade but the got a none pro. I compared it with the other freud pro blades I had and could not see any difference. Anyway I queried with the supplier who queried with freud and the answer I was given was that freud was dropping the pro branding so depending on age of stock you would either get a pro marked blade or not.
In practice I have not found any issues with the blade but it would be nice if freud would confirm this officially on their website. Would be interested in anyone else has been told a similar story.
