Tim, I don't consider myself an expert at sharpening but the Edge Pro does allow me to achieve "scary sharp" edges. Except the one ProTech Brend 2 auto, that I like, which causes me fits. I can get it sharp and I did completely skin a black bear with it but I'm unable to achieve that razor sharp edge we all love.
I even had Rick Menefee place a hollow ground edge on it and it arrived sharp but not nearly as sharp as the fillet knife he made me. Plus, the edge didn't hold up, and I don't have the means to replicate the hollow ground edge.
I know you have a history with these blades. Care to share some advice? I suspect wonky heat treat.
Posted this then realized this is a total hijack of your M4 thread - my apology.
