Okay, Is there a better way or another way?
Yes,there is another way.
Is there a better way?
It is what ever does the job you want and you are comfortable with.
There is a saw blade for the Ex-acto knife
It is as thin as the #11 Blade.
Bad cell phone pic but I'm sure you get the jest of it.
With any saw blade for a Dremal, you'll need to learn Gentle pressure.
They will get caught up when cutting and Zip around what your trying to cut
and cut what you don't want to cut (i.e. Fingers)
