Thank you everyone for your replies. I have been practicing since one week. I do this at night with lots of time and cover small areas. I havent been applying much pressure either and the blades are indeed sharp. The blade doesnt glide smoothly and feels kinda rough, I have tried doing with grain and against the grain and it still feels when I touch with my hand.

I guess its all about practice and patience as suggested - glad to know that Im not the first one who felt and been thru this same way.
