Before he could speak, a ball whose every edge was a razor-sharp blade cut through the air toward him.

The terrified man's eyes crossed as he looked down at the razor-sharp blade and swallowed.

It's kind of like a Roomba but bigger and with three razor-sharp blades.

It had a red handle and a honed, razor-sharp blade.

She felt the razor-sharp blade against the front of her neck, pressing in ever so slightly.

It would take just a flick of the razor-sharp blade against his throat.

A small, razor-sharp blade suddenly protruded from the tip of it.

Something sinewy and dense gave way before the razor-sharp blade.

He grabbed the man's hair and brought the razor-sharp blade across the throat.

He hesitated for a moment, the razor-sharp blade in his hand, and I offered him my right hand.
