Marker Gauge

Bye bye pencil and ruler. Why hello Marker Gauge !

This quirky tool has converted expressions of exasperation to overwhelming joy ever since it was released. The reason is simple – it’s such a brilliant time saver AND it’s accurate!

Marking out is fundamental to cutting a perfect window mount and one of these saviours is included in every kit. It is also available as an accessory.

Burnishing Bone

finishing touches make all the difference,

what it does and when to use it…

The burnishing bone is the best way to smooth down the slight lifting of raised mount board fibres that can sometimes occur along the edge of a cut. Although almost invisible to the naked eye, such slight imperfections detract from the professionalism of the finished mount if left untreated.

NB. Different mountboard finishes and textures are more susceptible to raised fibres than others so don’t necessarily feel that this is a reflection on your mount cutting skills.

For subtle mount decoration, the bone itself also makes an effective embossing tool. By pressing down on the mount, you can score an indent into the surface of the mount board.

Blades Blades

Longridge has designed a blade specifically for cutting mountboard with a progressively honed profile. This significantly reduces the chances of scuffing when the body of the blade passes the newly cut edge.

Manufactured from surgical steel, it also has a sharper edge than the traditional 270 general purpose utility blade, providing cleaner cuts for longer.

These blades fit all Longridge cutters and will fit any cutters designed to take the 270 size blade.

Longridge L030

General Purpose 270

Designed specifically to cut mount board

Designed to cut carpet, not mountboard

Rolled to an edge = clean, smooth, easy flow cut

Stamped out = creates friction, requiring more pressure and force

Surgical steel = stronger, durable, longer lasting

Mild tool steel = wears more quickly


Oiled  = leaves oil smears on early cuts

The specifically designed engineered cutting mat for bevel cutting. 

Why do I need it?

When bevel cutting, you must cut into a cutting medium otherwise you will damage the base and blade tip. It also prevents feathered edges. Avoid at all costs!

By default, tradition has used what is to hand, eg. waste mount board, self-healing cutting mats etc.

“A discipline as specialist as mount cutting merits a similarly specialised cutting medium” says MD Chris Longridge

SprintMat is specifically designed and engineered as a cutting medium for bevel mount cutting. SprintMat fibres are aligned in the direction of the cut.

  1. It is easier to cut with the grain rather than against it. Less force = cleaner cut.
  2. The flat, laminated surface, combined with the aligned fibres, positively help support the blade when cutting and makes for a cleaner, more accurate cut.
  3. The best incentive: All this reduced effort extends your blade’s life!
