In the Sacred Village thing. It is between White Forest and Undella Town from what I remember. On the Route between them go up the waterfalls. Go in the opening in the forest. There is an item Pokeball or use Dowsing Machine and you will find it.
I think u find it near the last gym
There is no razor fang in emerald as Gliscor does not exist in the third generation.
In order to get a razor claw you need to have Gilgar hold the razor fang at night and level up. You can find a razor fang on Route 214.
go to route 11 but you must have the HM waterfall. it's there.
In order to obtain a Razor Fang, you need to be able to trade it from either Heartgold, Soulsilver, or Platinum. Those are the only one's I know that have Razor Fang.
Catch gligar and hope you get lucky.

Route 11
In Pokémon White 2, you can buy the Razor Fang at the Gear Station and in the Pokémon World Tournament building provided you have enough Battle Points that will match its price.
