The Stanley FatMax Pocket Knife excels in situations requiring a reliable, adaptable cutting tool. Its combination blade is a significant advantage:
Serrated Edge: Ideal for tough materials like rope, cordage, webbing, or fibrous insulation, where a sawing action is more effective than a push cut. Think cutting through thick packaging straps on a job site or trimming a stubborn piece of carpet.
Straight Edge: Perfect for general utility tasks such as opening boxes, scoring materials, stripping light-gauge wire, or making controlled cuts on wood, plastic, or drywall. This edge provides cleaner, more precise cuts for detailed work.
The heavy-duty design means it stands up to the rigors of a workshop, construction site, or outdoor environment. The slim, finger-contoured aluminium handle ensures a firm and comfortable grip, even when wearing gloves or performing repetitive tasks. The liner lock provides essential safety, ensuring the blade remains locked open during strenuous cuts, giving you confidence in its stability. Its one-handed opening via the thumb stud is invaluable when your other hand is occupied, allowing for quick deployment in busy work scenarios or emergencies.
This knife is a workhorse for:
Construction & Trades: Cutting insulation, opening material bags, scoring drywall, trimming excess materials.
DIY & Home Improvement: Breaking down boxes, minor repairs, crafting, gardening tasks.
Outdoor & Utility: Cutting cord, opening tough packaging, general camp utility.
Your Stanley FatMax Pocket Knife comes ready for use. Simply remove it from its packaging. Before first use, familiarize yourself with the thumb stud for one-handed opening and the liner lock mechanism for safe closing.
Opening: Push the thumb stud firmly forward and up with your thumb until the blade fully extends and the liner lock engages with an audible click.
Closing: Carefully push the liner lock (the metal bar inside the handle near the blade pivot) to the side, away from the blade's base, while simultaneously folding the blade back into the handle with your other hand. Keep fingers clear of the blade path.
This knife is compatible with a wide range of cutting tasks requiring a utility blade. It's designed for cutting materials such as:
Cardboard and packaging
Rope, cordage, and fabric
Plastic sheeting and zip ties
Light wood or composites
It is not intended for prying, chiseling, or heavy-duty wood chopping.
Proper care ensures your knife remains sharp, safe, and extends its lifespan.
Cleaning: After each use, especially if cutting dirty or corrosive materials, wipe the blade clean with a damp cloth and then dry thoroughly. For stubborn grime, use a mild soap and water solution, ensuring to rinse and dry completely.
Lubrication: Periodically apply a small drop of lightweight machine oil (e.g., mineral oil, gun oil) to the blade's pivot point. This will keep the opening and closing action smooth. Wipe away any excess oil.
Sharpening: The straight edge will require regular sharpening. Use a quality sharpening stone or knife sharpener at a consistent angle (typically 20-25 degrees). The serrated edge requires a specialized sharpener designed for serrations; common sharpening stones are not suitable.
Storage: Store the knife in a dry place to prevent rust, with the blade securely folded into the handle. Keep out of reach of children.
