'Sharp' in the Bible

And there arose a sharp contention, so that they parted asunder one from the other, and Barnabas took Mark with him, and sailed away unto Cyprus;

And he had in his right hand seven stars: and out of his mouth proceeded a sharp two-edged sword: and his countenance was as the sun shineth in his strength.

and to the angel of the church in Pergamum write: These things saith he that hath the sharp two-edged sword:

And I saw, and behold, a white cloud; and on the cloud I saw one sitting like unto a son of man, having on his head a golden crown, and in his hand sharp sickle.

Another angel came out from the temple which is in heaven, he also having a sharp sickle.

And another angel came out from the altar, he that hath power over fire; and he called with a great voice to him that had the sharp sickle, saying, Send forth thy sharp sickle, and gather the clusters of the vine of the earth; for her grapes are fully ripe.

And out of his mouth proceedeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness of the wrath of God, the Almighty.
