Shedding Blade

What comb / blade for my German Shepherd?
I had to come to for advice and again, everyone is always so helpful.
I would like know what people recommend to use for washing my German Shepherd? I have a standard comb and brush, but seems to have forever and I do not seem very far, skin just keeps coming. I read about shedding leaves, but many are sure what type / length of the tooth, so I would say is long hair medium and is 7 months old. Its just started to fall into the masses and still has puppy fur right below. Do not you think it would start to move yet but it seems to lose all year!
Years ago I used to pour out on the road my mom German shepherd, and it took me 3 days. The faster You can get the dead layer, the less shedding will do. Now I've tried my robbie leaf shedding, but did nothing. So my suggested FURmantor abuser, and I love this tool. It is expensive, and I'm very happy with how it works. When the warmer weather that approached vacuuming every day. Now I can go longer. Brush it, then give him a warm bath to relax even more coat, dry and brush it again. You'll feel better too. Coat of the Dead is irritating for a dog. I just got out of some of the hair in the yard to pick up birds use their nests.
