Has Dan ever commented on the thumb ramp and why it's there. I was looking at some bark river steel and happened to come across a discription of the thumb ramp. They state it's not designed to have the thumb behind it, but actually in front of the thumb ramp when you choke up. They say the back of the thumb ramp is scored to use with a firesteel.

Thought that was a great idea. I will try to use the back of my thumb ramp with a firesteel.
