Stanley 10‑817 – FATMAX® Xtreme Snap‑Off Knife

The Stanley 10‑817 FATMAX® Xtreme Snap‑Off Knife is a professional‑grade, heavy‑duty cutting tool engineered for demanding jobsite environments. Designed with a die‑cast all‑metal body, it delivers exceptional strength and durability, making it suitable for industrial applications and continuous use.

This knife features a 25 mm wide snap‑off blade, providing a large, rigid cutting edge for tougher materials like insulation, carpet, linoleum, roofing shingles, foam board, and dense packaging. The blade knob lock secures the blade firmly in place during heavy‑pressure cuts, ensuring stability and precision.

A diamond‑textured, slip‑resistant grip enhances handling, even in wet or gloved conditions. The integrated stainless‑steel blade cartridge stores up to four spare blades internally, enabling quick, tool‑free blade changes that keep work moving efficiently. The blade advances with a smooth sliding mechanism and can be fully retracted for safe storage.

The 10‑817 is part of the FATMAX® Xtreme line, known for high‑endurance tools built for professional contractors.
