If its a metal one you are talking about, then I only use the metal if the horse is crusted in mud or as a shedding blade if all others have gone missing :p
Heres my grooming routine.
1.Use a rubber curry everywhere (even gently on the legs if muddy.)
3.Soft Brush (If time permits)
4. Wipe down legs if I didn't have time to hose. (As in I'm sometimes a little late for my lessons D:)
5. Wipe down eyes/nose/mouth etc.
6.Flyspray (In the summer)
