Gonytia Straight Mat Cutter Handheld 90° — 10 Replacement Blades, Adjustable Depth & Guided Rail

Gonytia Straight Mat Cutter is a handheld 90° mat board trimmer that delivers consistent straight cuts and comes with 10 replacement blades for extended use.

If you frame artwork, create presentation boards, or trim foam core and vinyl, this tool gives you fast, repeatable straight cuts without the bulk of table-mounted cutters. Designed for hobbyists, framers, and graphic producers, the cutter balances control and safety with a guided rail system and an adjustable blade exposure so you can match the cut depth to the thickness of the material.

How does this cutter keep blades from over-cutting or damaging the work surface?

The cutter features an adjustable blade exposure mechanism so you dial in the right depth for foam core, mat board, or vinyl. Reducing blade exposure prevents gouging the work surface and prolongs blade life.

• Thumb-adjust or tool-adjust blade depth to suit material thickness.
• Includes 10 spare blades so you can replace dull edges quickly.
• Precise settings reduce the need for multiple passes and surface damage.

Can I trust this for perfectly straight cuts every time?

Yes — the cutter uses integrated nylon guide rails that stabilise the cutting head and glide along a straight rail for accurate, repeatable cuts. For freehand or specialty cuts, the guides are removable so you can use the cutter against a ruler on your work surface.

• Nylon guides keep the blade aligned for clean, parallel edges.
• Guides detach with the supplied hex key for freehand trimming.
• Ideal for long, uninterrupted straight cuts on large boards.

What materials and cutting jobs is this tool best suited for?

This cutter handles a broad range of substrate types including acid-free mat board, foam core, and thin vinyl sheets. It excels at straight-edge trimming and finishing edges but is not designed for creating beveled or decorative bevel cuts.

• Foam board and poster board trimming for displays and models.
• Mat board trimming to size for framing and mounting photos.
• Vinyl and other flat sheet materials requiring straight, accurate edges.

How comfortable and safe is it to use repeatedly?

Ergonomics and safety are built into the handle and cutting mechanism: a non-slip grip plus a press-to-cut action give you control while minimizing hand fatigue. The design keeps fingers away from the blade and the integrated guide reduces slips for safer operation.

• Non-slip ergonomic handle improves grip during long jobs.
• Press-to-cut mechanism gives steady, controlled pressure.
• Blade storage and included spares reduce downtime and handling risks.

Who this is for: The Gonytia Straight Mat Cutter is suited to picture framers, art students, designers, exhibition preparers, and hobbyists who need an efficient, low-footprint trimmer for straight-edge work. If you want consistent, professional-looking borders and edges without investing in a large bench cutter, this handheld 90° mat board cutter provides a reliable, portable solution.
