✕DO NOT FORCE THE FIT
- Not yet the recommended buy for a single known shaver — that answer is the dedicated pack whose width matches the head, on plainly stronger records (§4).
- Not blades for freehand use: no tool in the store besides the three shavers is built to hold these, and a bare wall-width razor edge has no unheld application.
- Not a putty-knife or utility-knife consumable.
- And not a documented snap-off product — whatever the title suggests, this corpus has not authored that mechanism into existence ⚑.
