Is there a big difference?
I had the normal blade on for my t outliner and it was good. After some time it cad gotten a broken tooth and I desided to try something different. I ordered this blade with low expectations because I had herd mixed reviews, but the deep really help grab the hair and leave a nice crispy line.¬†
ProsLeaves a nice edge, and it's very sharp
ConsIt doesn't come with a blade protector like wahl products so if you carry it in a case there's a good chance you'll brake a tooth on it.
