    For clarity, this is a bellied hollow grind.

    Hard to see in that picture. Here's one from the toe.

    As mentioned, they didn't really show up until Carl Friedrich Ern invented the Hexe machine (German for witch) in the 1880s-90s. It was a double wheel grinder which mainly made it more practical to produce full and extra hollow grinds. The bellied came later and was patented or attempted to be patented. There is an article around here somewhere about it.

    Found this on the Koraat Razor configurator. Hope it aids the discussion.

    Thanks for sharing this. I saved a copy when I ordered my first Koraat so I could reference. Hence where I got the "bellied hollow" description
