The Thingamejig Scribing Tool saves you time while still delivering the precision results you need. Thingamejig's single handed use frees up one hand to steady the item you are scribing. Adjustable blade height ensures accurate marking with the ability to accurately retrace your lines. Thingamejig is constructed from lightweight anodized aluminium so it won't rust. The blades are made from highly durable tungsten carbide. Thingamejig scribes laminates, painted items, stone, soft metals, timber, veneers and more. Single handed use reduces risk of falls by freeing up one hand to steady yourself if scribing while standing on a ladder. Reduces time spent in prone position as requires only one hand to operate.
