You might be more likely to get an answer by starting a whole new thread asking your question.Im brand new here. And this is my first post. Ive been searching for info on the Celcon sheath material, and cant seem to find out whether it has glass re enforcement in it like the handle or not? Ive had Cold Steel knives with the Secure X material(which is glass re enforced) and I don't like it. seems to dull the edge to the degree it touches it. Thanks
