I have a problem with making a left hand tool with Motor6D

I’m trying to make a left hand tool with a tool holding animation made with Motor6D.
First I made a Motor6D Animation. Heres the Video I used:

I just changed the RightHand with the LeftHand. Then I used this Tutorial to make a tool holding animation: (Without using Toolgrip plugin)

Then I tested it and the Animation was correct, but the Tool switched to Right hand.
Then I changed the name of Handle part and also disabled tool.RequiresHandle. But when I tested it the animation didn’t played and the Tool weren’t there.
Anyone know how I can fix this or know a other way how to make a left hand tool that I can animate? I’m pretty new with Tool animations.
