I'm looking for really sharp openings

Hello. I am looking for openings, which seriously are sharp (even better when they are less known!).

Currently I play Latvian, Urusov, Scotch, Italian-Koltanovsky and Greco gambit (1.e4 e5 2. Bc4 Nf6 3. f4).

I however would want to have a greater reperoire and an answer to 1.d4 and 1.c4, and also 1.f4 and King's gambit.

Can any attacking maniac share some of their openings?

Thank you.

 Wouldn't a gun be more effective? It needs more theory learning tho'

Maybe try:

Englund Gambit:

1.d4 e5

The greatness about this opening is that the majority of players are not expecting this attack.

But beware, this opening can be refuted if the opponent knows what hes doing:

A Fun, Attacking Gambit

Here's another winner...
