Sorry, I searched for anything Doug said about the edge angle and couldn't find it. 30 sounds right since that is what he recommends in his knife review for a good survival knife. I keep my delica at 30. The serrated edge means I have to use the corner, rather than the flat side of the stone, but I will use the flat side for the mk1. Great advice.

I read on some knife website that a plain edge can be stroped on a the cardboard backing of a legal paper pad. Has anyone tried this?

We have a great knife shop at the mall (the owner is very informative and does nice work) and they did a bang up good bringing my serrations back to life on my delica. I described the mk1 to them and they confirmed - steal of that quality in a benchmade handle would indeed be pricey. The mk1 is a deal.
