Utility Knife STANLEY 18 mm with integrated breaker and slide MPP, replaceable breaker blade

The STANLEY Utility Knife 18 mm with integrated breaker and slide MPP is a hand-held cutting tool designed for controlled, repeatable cutting tasks. It accepts standard 18 mm snap-off blades and includes a built-in breaker for safe removal of dull blade segments. The slide MPP mechanism provides smooth blade extension and retraction for precise depth control during use. Suitable for cutting cardboard, carpet, plastic and similar materials in construction, packaging and workshop environments, this utility knife balances durability with straightforward maintenance.

Advantages

The integrated breaker eliminates the need for a separate tool to snap-off worn blade segments, improving on-the-job safety and convenience. The slide MPP mechanism offers reliable blade control with positive locking positions, reducing accidental blade movement. The body is engineered for repeated blade changes and straightforward access to the blade holder, allowing quick replacement of standard 18 mm snap-off blades. Compatibility with widely available blades keeps operating costs predictable.

Suitable for

• Cutting cardboard and corrugated boxes
• Trimming carpet and linoleum
• Scoring and cutting plastics and film
• General workshop and light construction cutting tasks

Key specifications

• Blade type: 18 mm snap-off blade compatible
• Blade breaking method: integrated breaker for snapping blade segments
• Blade control: slide MPP mechanism for extension/retraction
• Handle: hand-held utility knife body designed for blade changes
• Primary materials cut: cardboard, carpet, plastic, film

How to use

Extend the blade to the required cutting length using the slide MPP control, ensuring the blade locks in position before applying force. For straight cuts, maintain a steady hand and appropriate cutting surface; for thicker materials make multiple shallow passes rather than forcing a single deep cut. When a blade segment becomes dull, use the integrated breaker to snap off the worn segment along the factory scoreline, then retract or replace the blade as needed. Always keep fingers clear of the blade edge when adjusting or breaking off segments.

Usage recommendations

Use replacement 18 mm snap-off blades that match the knife's specifications and routinely check the slide mechanism and breaker for debris to maintain smooth operation and safe blade changes.
