I wanted some advice regarding my large Sebenza. I've EDc'd it on and off for over 10 years. It's been back to CR for a new clip, stud and maintenance one time over the years, and it's pretty much like new except for a bit of wear to the finish on the grips. But with all the attention newer steels are getting these days I find myself wondering if I should send it back again to CR and have a new CPM S30V blade installed. They charge $125, I think. Will I notice a big difference? I find the edge lasts ok on the old ATS blade, but I'm pretty careful with it.
