I have a bag that say p2 blades but look and feel identical to p4. Since I was smart and pulled it out to compare to the p3 blade. I don't know which is which.
The part number is even same on the blade too.

With the Phantom line abandonment and no way to delete the account so goes the posts.

They both say 9450.
