Save time and get an accurate finish all with one hand. The Thingamejig scribing tool is constructed with lightweight anodized aluminum which means it won’t rust. To ensure precision results, the tool’s measuring ruler has been laser cut  with imperial inches. Plus the ergonomic three-finger design fits comfortably in your hand and allows for easy maneuvering.

The Scribing Tool set includes:

  • Scribing Tool
  • 3 Tungsten Carbide Blades
  • Foot Pad Cover
  • Allan Key
  • Instruction Booklet
  • Protective Case

Any task, any surface

Perfect for cabinet makers, carpenters and stone masons, our Scribing Tool has been developed using patented technology. This ensures a gap free finish when fitting cupboards, bench tops, architraves and skirting boards.

Constructed with light-weight anodized aluminium and tungsten carbide blades, our Scribing Tool marks the following surfaces:

Laminates, painted Items, stone, soft metals, timber, veneers and much more.

 ...And no more chipping!

Using blades to mark your lines instead of pencil means that you are creating a guide line ready for trimming. This cut reduces chipping when scribing and trimming across timber grain, paints and laminates.

Not to mention, your standard pencil will get blunt and there's nothing worse than a pen that's run dry!


1. Adjustable heights

Our Scribing Tool's blade heights can be adjusted to the most accurate measurements using the laser cut ruler. These are available in both metric and imperial measurement.

2. Scribe into corners

The scribing points of the triangular blades allow you to use a single hand to get into those hard to reach corners you previously couldn't mark.

3. Retrace your lines

The fact your scribing tool is positioned at a fixed height means that you can go back and retrace your lines without any shifting. The protective foot pad cover also stops any marking of walls.

The Thingamejig is a precision scribing tool invented by an Australian cabinet maker who installs millwork and cabinetry. Instead of marking with the usual pencil, it scores the material with sharp carbide blades.

The tool consists of a three-winged head with replaceable carbide cutters screwed onto each. A threaded shaft runs through the center, allowing the head to be raised and lowered in relation to the foot—which bears against the surface being scribed to. Once the setting is dialed in, the operator secures the shaft with a lock nut.

The scriber has an ergonomic three-finger grip, making it comfortable to hold and allowing the operator to apply pressure where and when needed. In use, the blades score easily, breaking through the finish so there's no need to worry about chipping. The tool works amazingly well on cross-grain veneer—nearly eliminating the fear of tearing out grain while making the cut. I can usually get a successful scribe in one or two strokes, depending on the hardness of the material. Laminate sometimes takes an extra stroke to break through the surface.

The triangular blades can be rotated to provide three fresh edges. I have been using the Thingamejig for about a year and the blades are ready to be replaced. This is not a tool to be tossed around. (I dropped it once and chipped a blade.) Like any precision device, it needs a home and should not be carried in your tool pouch. The Thingamejig comes in a snap-top plastic bin, which is a good thing to store it in.

The scriber includes a non-marring plastic cover that fits over the shoe and prevents it from damaging finish surfaces. I use it nearly all of the time and recommend keeping some extras around because they themselves are easily damaged. If you use the scale, remember to deduct 1/32 inch for the thickness of the cover. I rarely use the scale; I simply find the largest gap to be scribed and adjust the height of the winged blade, then snug the lock nut.

There are pros and cons to scribing with blades instead of pencils. Blades work best on painted and prefinished material, where the finely scribed line is easy to see. By breaking through the finished surface, the blades make it possible to cut to the line with a jigsaw without having to worry that the finish will flake off (I usually touch up with a belt sander anyway). The Thingamejig is not the best choice for scribing unfinished wood, because the finely scribed line is hard to see on that material. I use this tool when scribing to straight, smooth, and flowing surfaces – as when fitting countertops, cabinet fillers, and moldings to ceilings, walls, and floors. The Thingamejig is not an all-purpose scriber and can't be used to scribe around moldings and rough surfaces such as stone. Fortunately, there are plenty of other scribing tools that can do those things.

I liked this "thing" the moment I opened the box. Everything about it says quality: the precise machining, the laser-etched scale (metric or imperial) on the shaft, and the triangular carbide blades.  With an $80 price tag, this scriber certainly is not for everyone. Some folks will say they can achieve the same result with a $3 compass scriber; they can't – at least not efficiently. The Thingamejig will pay for itself by increasing the quality of your work and reducing the amount of time it takes to do it. If you are like me—a scribing maniac—then you're going to love this tool. It can be purchased at many industry suppliers, which for some reason are mostly located in the Eastern half of the U.S.
