How do GripForward and the rest (GripPos, GripRight, GripUp) work?

I’m trying to change the code for Teddy Bloxpin gear to reuse it in my game, but I can’t figure out how to change grips properly. For anyone who hasn’t seen the code:

	Tool.GripForward = Vector3.new(1,0,0)
	Tool.GripPos = Vector3.new(.5,-1.5,-1.56)
	Tool.GripRight = Vector3.new(0,-.707,-.707)
	Tool.GripUp = Vector3.new(0,-.707,.707)

Can anyone help? Here’s what it looks like and what it should look like instead:
