Pausing animations in Unity

Hi, I have a question about animations.

l am trying to animate an attack animation for my 2D character who uses scythe. The problem arises when he hits with his weapon, I want to basically pause the animation for the dramatic effect. He just swung that weapon and basically since it was a more powerful blow scythe is let’s say stuck for a lil bit. The next thing that should happen is he should slowly bring his weapon to the default position.

So how do I do this?

When I try to animate it it looks like he is just going full circle.
Thanks in advance.
