Will there be swords in the last hour?

It says in a Hadith that when the Muslims conquer Constantinople, they will hang their swords by the olive trees and Satan will cry about the Dajjal. > Abu Huraira reported Allah's Messenger (ﷺ) as saying: The Last Hour would not come until the Romans would land at al-A'maq or in Dabiq. An army consisting of the best (soldiers) of the people of the earth at that time will come from Medina (to counteract them). ... > > A third (part of the army) which would be constituted of excellent martyrs in Allah's eye, would be killed and the third who would never be put to trial would win and they would be conquerors of Constantinople. And as they would be busy in distributing the spoils of war (amongst themselves) after hanging their swords by the olive trees, the Satan would cry: The Dajjal has taken your place among your family. ... -- Sahih Muslim 2897 (sunnah.com ) If they are using swords, what will happen to guns and modern warfare?
