He cut the meat using a Western knife.

His eyes were sharp, as if nothing could be hidden.

His sharp gaze pierced me.

I am amazed at his keen observation skills.

He took the sharp weapon in his hand and advanced towards the enemy.

His knife is very sharp.

He sharpened the tip of his sword.

The edge of this knife is sharp.

He is my previous boyfriend.

This chicken wing tip is very delicious.
