Robbers wielding a samurai sword and a large knife assaulted staff at the Esso Service Station in Mayfield Road, Cross in Hand.
The pair entered the store just after 3am on Saturday (March 25) – one shop worker was hit over the head and the other was pushed to the ground and dragged along the floor.
The two suspects then made off empty handed in a vehicle, which may have been parked in a nearby car park say police. Officers said the vehicle then headed off at high speed towards Heathfield.
The victims, both local men, aged 30 and 49, were taken to Eastbourne District General Hospital to be checked over and discharged later the same day.
Police say the suspects were white, wearing black or dark clothing, and had local accents.
