Silverline Snap-Off Knife

The Silverline Snap-Off Knife is a versatile, general-purpose utility knife designed
for fast, clean cutting in a wide range of site, workshop and DIY applications. Featuring a
segmented snap-off blade for instant sharpness and a robust, easy-grip body, this knife
is ideal for decorators, floor layers, electricians, plumbers, builders and home users.

The Silverline Snap-Off Knife is designed for fast, convenient cutting with minimal
downtime. The multi-segment blade is scored into sections; when the cutting edge becomes dull,
simply:

• Extend the blade slightly,
• Use the integrated snap-off cap (or pliers) to break off the worn segment,
• Push the remaining blade back in – and you have a fresh, sharp edge ready to work.

Commonly available in 9mm or 18mm blade widths (depending on model), this knife is suitable for:

• Cardboard and packaging,
• Plastic sheeting and film,
• Plasterboard joint tape and scrim,
• Floor coverings, vinyl and carpet backing (with care),
• General trimming, scoring and light cutting tasks.

The plastic or metal body (model dependent) is shaped for a comfortable, secure grip and often
includes a rear blade snap-off slot for safe snapping of worn segments.

Typical Use Cases

• Decorating & finishing – trimming wallpaper, masking tape, caulk, filler and sealant nozzles.
• Flooring – cutting and trimming vinyl, underlay, carpet edges and floor protection sheets.
• Electrical & plumbing – scoring and cutting cable sheathing, conduit tape, pipe lagging and packaging.
• General construction – opening boxes and bags, trimming sheet materials and insulation facings.
• DIY & craft – model making, craft work and light duties around the home and workshop.

Features & Operation

• Blade type:
  • Snap-off utility blade with multiple scored segments.
  • Typically 9 mm (slim) or 18 mm (heavy-duty) depending on the specific Silverline model.
• Blade extension & retraction:
  • Thumb-operated slider moves the blade in and out of the body.
  • Allows you to set the cutting length for precise control.
• Blade lock:
  • Models typically feature auto-lock or screw/slide lock to hold the blade
    firmly during use.
• Body & grip:
  • Durable plastic or metal body with ribbed or rubberised grip areas
    (model dependent) for comfort and control.
  • Often includes an integrated blade snap-off slot in the end cap.

How to Use the Silverline Snap-Off Knife

1. Set the blade length:
   Push the thumb slider forward to extend the blade to the required length. Lock if your
   model has a screw or slide lock.
2. Make the cut:
   Hold the knife firmly and cut using steady, controlled pressure. For straight cuts,
   use a straightedge or guide where possible.
3. Snap off a dull segment:
   • Retract the blade until only the last scored segment is visible.
   • Remove the end cap or use the integrated snap-off slot.
   • Bend the exposed segment downwards to snap it off cleanly along the score line.
   • Dispose of the snapped blade piece in a safe sharps container or wrap securely.
4. Retract after use:
   When finished, fully retract the blade to minimise the risk of accidental cuts and
   store the knife safely.

Safety Information

• Always keep the blade retracted when not in use.
• Use sharp blades with care – avoid excessive force and always cut away from your body.
• Wear cut-resistant gloves and eye protection where appropriate, especially when cutting
  tough or awkward materials.
• Dispose of snapped blade segments and old blades in a safe manner (dedicated sharps box
  or well-wrapped in strong tape/cardboard).
• Keep out of reach of children.

Frequently Asked Questions – Silverline Snap-Off Knife

1. What blade size does the Silverline Snap-Off Knife use?

Silverline snap-off knives typically use either 9 mm (slim) or 18 mm (heavy-duty)
blades, depending on the model. Check the product description or stamping on the body to confirm which size your
knife is designed for.

2. Can I use generic snap-off blades?

Yes – most standard snap-off blades of the same width (9 mm or 18 mm) are compatible.
Always:

• Match the blade width to the knife body, and
• Ensure blades are high-quality and undamaged before use.

3. How do I safely snap off a blade segment?

Extend the blade so that only the last segment is exposed beyond the front of the knife. Use:

• The integrated snap-off cap/slot on the knife, or
• A pair of pliers,

to bend the segment downwards along the scored line until it snaps cleanly. Dispose of it in a
safe container.

4. Is this knife suitable for heavy-duty cutting like plasterboard or thick rubber?

Snap-off knives are ideal for light to medium-duty cutting (card, vinyl, plastic sheet, thin board).
For very heavy-duty tasks (e.g. multiple layers of plasterboard, thick rubber, dense insulation), a
heavy-duty fixed-blade utility knife may be more appropriate and durable.

5. Can I use the Silverline Snap-Off Knife for precision craft work?

Yes. The 9 mm versions in particular are well suited to finer, more detailed cutting
such as trimming paper, card, vinyl and thin plastics. For very intricate work, a dedicated craft knife
may offer even more control.
