The HYDE TOOLS 42100 is a utility knife blade sold in a 5-pack, designed for cutting tasks across a wide range of trade and general-purpose applications. Each blade measures 2.5 inches in overall length and is built to the standard utility knife profile. The 42100 fits the standard retractable and fixed-handle utility knives found on most job sites. HVAC technicians, plumbers, electricians, drywall installers, flooring mechanics, and general contractors reach for this blade type daily for scoring, trimming, and cutting insulation, strapping, sheathing, and packaging materials.
This 5-pack is suited for residential and light commercial work where frequent blade changes are standard practice. Keeping fresh blades on hand reduces drag, improves cut quality, and lowers the risk of slippage from a dull edge. The standard 2.5-inch utility blade format means these drop into most common utility knife handles without modification, making them a straightforward consumable replenishment for any trade toolbox or service van.
Designed as a standard-format replacement utility knife blade compatible with most retractable and fixed-handle utility knives that accept the common 2.5-inch blade style.
Blade replacement should be performed by a qualified tradesperson following the knife manufacturer's blade-change procedure. Always retract or lock the knife before changing blades. Use a blade disposal container to safely handle dull or used blades. Keep blades away from unprotected skin during handling and storage.
