From C Glen Cummings, the inventer:
"Over the years, I realized there was a need for an instrument to carve a post dam. After 2 years of development and focus groups, I came up with a combination of the most functional angles and curvatures paired with a comfortable handle. The result was better than expected. Not only does it carve a perfect post dam, it also works well trimming dies, scribing a beadline, carving the land area, picking bubbles, indexing casts and more."
