✕CHOOSE A DIFFERENT TOOL WHEN
- Not the close-control tool: shaving flush, steering small gaskets, notching at boxes — the work that happens under the fingertips — belongs to the 4", and assuming otherwise wastes both knives.
- Not the everyday general knife for a bench that never sees thick stock: that is the 6"'s seat, and the reason the middle rung exists.
- Not the insulation specialist: daily batts, rigid foam board, and foam-core panels are the 60118's claim by name , and a plain edge in binding material is working uphill.
- Not a belting or mill knife — the industrial .083" series (its 8" member 60780 most directly) carries that duty at a heavier gauge.
- Not a machete, pry, or scraper: length invites leverage, and leverage against the flat of a riveted 1" blade is abuse, not technique.
