This tool is much better than the mini ones that might come with a watch- the mini ones don't give you the leverage on really tight watch bands.

The process for creating the flat fork is to grind the surface until its very thin. Mine was over-ground, and either melted or caught fire, and one of the tines is visibly warped/bent, and blackened. However, it still works for its intended purpose, and I can fix any other blemishes, so no worries.
