Mount Cutting - Precision Engineering

STAGE 1: Investment – Why?

Art, needlecraft and photographs are usually framed with mounts under glass. Standard, inexpensive size frames are readily available in today’s market. However, finding a mount to suit your work is another challenge. Standard size mounts are often the wrong size and colour and of varying qualities.

Why struggle to fit your image into a mount the wrong size? Invest in a decent mount cutter and start producing bespoke mounts in your own home, to suit your work, hassle free.

STAGE 3: What to look for?

Buying a mount cutter should be a one-off event. It’s important to make the right choice.

Blade Quality

Cutting technology is a major consideration. Look for blades made from high quality surgical steel. These are dry from new rather than the lesser quality oiled blades which have a tendency to leave oil smears on the mount board. Standard 270 utility blades are ‘stamped’ to a point, rather than ‘rolled’ which means that they are weaker and more likely to flex.

Needless to say, Longridge have worked with the UK’s leading blade manufacturer to produce the former!


Look for a tool to help you mark-up efficiently and effectively. Using a ruler and pencil can be laborious and very time consuming – hence Longridge’s development of the Marker Gauge.


Connectivity is key. Instead of using a meagre cutting mat, the cutter and rail should lock onto each other and attach onto a solid base. The rail needs an integral mount stop and rubber lining to stop the mount from moving when bevel cutting. This connects all components together so that the operation runs smoothly and true to the markings, without curvatures.

Working in tandem with the base, when bevel cutting, should be a cutting medium to prevent feathering.

Developed by Longridge is SprintMat; a unique flat laminated board with its fibres aligned in one direction, the direction of your cut. The result: less blade drag and waver, minimal effort and a superior finish – it also helps the blade last longer too!


Ensure that the system has an accurate squaring facility and straight cutter for initially cutting the mountboard down to size. The exterior must be square in order for the marking and cutting of the window to be square as well. This is often overlooked. Be aware that some cutters cut the window edge a couple of millimetres or so to the side of the line. This requires the user to adjust for the inaccuracy every time. Longridge systems are calibrated to cut on the line with razor sharp corners.

Cutter Control

First, ensure that you can adjust the blade depth so that it corresponds to the mountboard thickness. Secondly, avoid overcutting by ensuring there are cutter stops and a mount board stop. These do the hard work for you by securing the mount in position and stopping the motion of the cutter when it arrives at the corner. Perfect corners are essential!

Left-handers beware!

Check that the mount cutter is specifically designed for left – handed use rather than just a crude adaptation. “We left-handers have rights too!” (Chris Longridge, Managing Director).

Straight from the box, you can feel the Longridge system exudes quality from our precision engineered components and the decades of experience that has gone into designing and manufacturing this British product.
