How do I make a Tool Holding Position?

Hello, I've been trying to figure out how to make a script for a tool so I can make both arms of my character hold the tool can someone please tell me how to do this?

well I know will most likely get a down vote for this but you should first of all put a humanoid on the baseplate, give him the tool and then configure how you want him to hold it, then in the script you type something like this (I can't remember the correct way of typing this script but here it goes)

CFrame.LArm.Rotation {paste the numbers of your humanoids LArm rotation from properties}
CFrame.RArm.Rotation {do same here except this time it's the RArm}

of course I said I will most likely get a down vote but hope this helps. P.S. I will update this as soon as I will get a glimpse of the script I've been looking at a long time ago...
