hey there got a sharperning question for u folks. say i use my EDC for light cutting say cutting loose strings, opening mail, cutting the packets of ketchup, u know everyday light work. sharperning is a minimum for me. and i think if im not wrong that the knife becomes blunt over time due to the burrs. this however according to a few of my friends, can be removed with leather (skinning the leather). the question is can i just use the ceremic file to touch up the edge, coz i dont intend to change the angle of it. will this be enough to bring back the edge to its production glory which by the way is shaving sharp?
