I lived 55 years before I found out the easiest, best way to shorten the screw posts when I am replacing the knobs on a piece of furniture. Am I the only one who didn't know about this?
I always hated the very long posts on new knobs. I would go to the hardware store and search for a replacement piece. Big hassle.
It's simple. You just get out your wire trimmers. Everyone has wire trimmers. Even when I only had a hammer and screwdriver I had a pair of wire trimmers. But I never knew they had this special function.
Just find the appropriate hole for the size of the post. Insert the screw post and squeeze. Really hard. IMPORTANT NOTE: The screw should always be inserted at the printed side of the wire cutters. That is opposite of the way this one is inserted.
