Get the 411 and don't look back. One of the best designed blades I've seen yet.
As for hair/dirt being the issue, both SF45ACP and I have Gerber Freeman in S30V that will process 10-15 deer before it needs a stropping.
Edge geometry seems more like the culprit and I'm also intrigued by the "need to get down to the heat treated layer."
Had the same issues with the Rodent Solution and the War Dog.
Dan, if you have some answers, that would be great. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
