How to make a tool's blade shake? (Chainsaw)

Hello, I am attempting to make an equipped Chainsaw and I want its blade to vibrate when it is out, what is the best approach to this?

I’m uncertain if Tweens or Lerp would work, but I have separated the handle and blade into two separate parts and welded them together.

If you welded the blade and handle togheter then you can just tween the C0/C1 property of the weld
