Basics of... Utility Knives

Utility knives are used to cut and trim a variety of building materials including: drywall, felt paper, wallpaper, rope & twine, plastic sheet material, fiberglass insulation and more. They can be divided into 3 general categories, Retractable Blade, Fixed Blade and Snap-off Blade.

Knives

Retractable knife

Retractable: a good choice for general use; offer the convenience of being able to quickly adjust the cutting depth of the blade. Plus they offer the safety of allowing the blade to be retracted completely into the handle when not in use.

Fixed Knife

Fixed: blades lock into a fixed, non-retractable position between the halves of the knife handle. This improves blade stability in severe cutting applications and allows the knife to accept special-purpose blades that are too large to retract into the handle.

Snap-Off Knife

Snap-off: built around a blade designed to snap off or break away in sections, providing a fresh, sharp cutting point without having to open the knife. These knives are a good choice for light- and medium-duty applications, or when adhesive materials like packing tape leave a residue on the blade.
