uncuttable
Resists all blades
Uncuttable describes something that cannot be cut—resistant to blades, scissors, or other cutting implements.
The term appears in marketing for protective gear and security products: uncuttable bike locks, uncuttable gloves for handling sharp materials.
Like many "un-able" formations, it often means practically impossible rather than absolutely so.
