Next time you change windshield wiper blades, remove the stainless steel supports from the old blade. You can cut them to any size you want; I cut them to about 6″. I round off the tips with a grinder and they are ready to use for mixing paint and epoxy  resins, prying the tops off Humbrol-style tinlets, smoothing filler putty, etc. They are easily bent or ground to shape and can be wiped or scraped clean for the next use.
