I just wanted to pass on a quick tip, that I just discovered.
Have you ever had a pair of scissors that started sticking, making it very difficult to open and close them while cutting?
Spray a little WD-40 on the hinge, then open and close them a few times, and they will get so much better. Make sure to dry them real well before using them, otherwise your next project might be covered in WD-40. You don’t want that!
