I could hear the metallic slither of an epée being drawn.

It was accompanied by the ominous metallic slither of chains.

There was the metallic slither of a sword being unsheathed.

Swords left scabbards with a sinister metallic slither.

Now and again, she heard the chink of spears, the faint metallic slither of chain mail, but even those sounds were muffled.
