Thank you to Unique Master Models (UMM) for generously providing an excellent tool for “field testing.” Thank you as well to the IPMS Reviewer Corps for letting me be an evaluator.
The tool is small, has a nice weight or heft in the hand, and does not flex easily. The scriber is strongly attracted to a magnet, but is not magnetic itself. The surface is highly polished. The longer deburring edge and the shorter scriber edge are sharp enough to start scribing right out of the cellophane package. The cutting edges should be easily honed as needed. The smooth sides moved easily along my steel straight edge. I pushed the limits a bit and found there was no flex in the tool that affected the “groove.” The primary tool design is for scribing lines in plastic, but I expect to discover other uses when the tool is in hand. Further, the tool has that somewhat undefinable sense of “feeling right.”
