Either assault or attempted murder. If you used a weapon it would be assault with a weapon/deadly weapon.

If no weapon was involved and it was NOT a sex assault, the SOL is 2 years.

In most jurisdictions I am aware of "Simple" Assault (meaning assault with nothing but your hands or fists) is a misdemeanor. It can be charged as a more serious crime depending upon the seriousness of the injuries inflicted on the victim.
