Here's where I show just how new I am! My next project is a camp/ chopper/ machette hybrid for my brother-in-law to use on his property for a multitude of tasks. Starting with a piece of 2" O1 I am going to flat grind a 1 & 3/4 inch high bevel to near finish, and then convex that to the finish edge thickness before heat treat. But when I go to put on the secondary bevel I am at a loss...how do you do this? Basically I'm asking what is a secondary bevel on a convex ground chopper, is it convex again? Or a flat grind micro bevel at 30 degrees (or whatever the suggested angle for this style of blade)? Thanks in advance for any help / insight, Cheers, Griff.
