So I guess I'm alone here, I quite like the Secure-x. Hasn't dulled yet.
Actually you are in the majority. Most Secure-Ex sheaths do not present a problem, which is why Cold Steel CS appears to be unaware of these issues.
However, there are sufficient numbers of reports of blade scratching, and the issue of blade dulling which has been around for a few years now, that CS
really should take a look. The Secure-Ex sheaths IMO are a good idea and design in general, better than many competitors. But the material and fit are an issue.
My 01-TM sheath poses no problems at all. My BBC has a sheath that has poor fit, sometimes I can not pull the knife out.
