So indeed this is a tactical knife/subforum. What things do you do with a Hinderer that are considered "hard use"? Do they require as much or more durability in the edge of the knife than a large chopping knife? I think it's a perfectly valid comparison if I can use an edge angle on 12 (Cold Steel Barong), 13 (Cold Steel Kukri Machete), and 16 inch (Cold Steel Panga Machete) blades that is lower than a folder with a 3 inch blade.
The OP has decided to lower his knife edge angle a little to 20 degrees/side. He may decide to go even lower, but that is up to him. I was just pointing out that for his uses, lower angles are plenty durable and will cut with less effort for longer.
