Stanley STA010150 SM9 9mm Snap Off Blade Knife

On a busy job, it’s often the small tools that get used the most. The Stanley STA010150 SM9 9mm Snap Off Blade Knife is built for those everyday cutting tasks that happen constantly—opening boxes, trimming plastics, scoring plasterboard paper, cutting tape, shaping foam, and cleaning up finishes—without adding bulk to your pocket or tool belt.

The SM9 features an impact-resistant, high-quality ABS plastic body designed to take the knocks of site and workshop life while staying lightweight and comfortable in the hand. A secure multi-position slide button lets you extend the blade in controlled steps, so you can set the right cutting depth for thin materials like film and tape, or extend further when working through thicker packaging and sheet materials. A pocket clip keeps it close at hand when you’re moving between tasks.

One of the key practical touches is the removable rear body section, which provides access to the blade carrier and snapping slot. That means when the blade edge dulls, you can snap off a segment cleanly and keep working with a fresh cutting point—ideal for repetitive cutting where sharpness directly affects safety and finish quality.

This knife is designed around standard 9mm snap-off blades, making replacements easy to source and cost-effective to keep stocked on vans and in workshops. For best results, pair it with quality 9mm blades suited to your material (general-purpose for packaging, heavier-duty options for tougher plastics or repeated use).

Professional use tips and safety

• Always extend only as much blade as needed—shorter extension improves control and reduces snap risk.

• Snap segments carefully using the built-in snapping slot and dispose of used segments safely in a sharps container.

• Keep fingers clear of the cutting path and retract the blade fully when not in use.

• Cutting knives are age restricted in the UK—ensure compliant handling, storage, and sale.
