First Use Experience

The initial use of the DMT Crystal Saver occurred right at my workbench, specifically targeting a small, sharp edge on a ceramic sample holder that had developed during a high-temperature experiment. I held the sample holder steady with a pair of fine-tipped tweezers, and with gentle, consistent strokes, began to work the diamond file over the burr. The half round file design proved particularly adept at conforming to the curved edge of the ceramic piece.

The coarse grit of the diamond immediately began to abrade the offending imperfection. I found the process to be surprisingly controlled; there was no tendency for the tool to slip or gouge, which is a common issue with less refined abrasives when working on delicate surfaces. This allowed me to focus solely on smoothing the edge.

I experienced no significant surprises or quirks during this first use. The ergonomic handle provided a secure grip, and the overall experience was one of efficient problem-solving. It was clear from the outset that this tool was designed for exactly this type of application.
