How do I rotate a mesh to fit a tool handle?

I want to make it so that instead of being rotated downwards when held, the mesh is facing upwards... How would I rotate this mesh? Sorry if it's a stupid or easy to fix question.

Thank you.

A. Change the GripUp property of the tool (I think)

B. Manually CFrame the tool's setting position in the output like:

ToolPlacementHere.Grip = CFrame.new(PosX,PosY,PosZ)*
CFrame.Angles(math.rad(Xangle),math.rad(YAngle),math.rad(ZAngle))

Of course replace the Pos and Angle to actual numbers.
