The specially designed blade in this Plasticutter scores and cuts Acrylic and other plastics up to 1/4" thick. The position and angle of the hardened steel cutting edge is the key to scoring not only Acrylic, but Plexiglas®, Lucite®, styrene, PETG, and other plastics. Blade folds into handle for safe storage, but snaps into place when opened. This tool is excellent for field work, such as installing lighting panels.
