What is a hollow grind?

A hollow grind is a way to grind your blade so that the bevels curve inward (concave) to meet at a point. This makes for an extremely sharp knife, but very fragile edge at the same time. It’s a difficult grind to achieve, even with the right tools and as such, you won’t come across a hollow grind too often in custom knives. That said, hunters sometimes prefer hollow grinds for skinning and dressing animals. Please refer to my article on the 8 Most Common Knife Grinds for more.
