The first application is to cut out your paper decals from a plastic model kit. The sharp carbon steel and fine tip make it easy to cut out the most complicated decals. Note: The sharpness of the scissors will last long if it is used only for paper decals. Do not use them for vinyl stickers as found in an R/C car kit.The second application is the trimming of R/C racing tires. R/C racing tires are usually soft and the burr produced during casting must be cut away.
