I used to touch-up Photo-masks ( by hand ) which had circuit lines which were 0.003 to 0.004 Inches wide . As I recall , that is about the width of a female human hair . Don't know much about Custom Knives , but you might be able to make some estimates of what the knife edge should be to split such a Hair . BTW , I have not been at all impressed with the few Customs I have purchased so far . They are beautiful , but NONE have been anywhere near Sharp enough to shave hand hair . With that said , I do not want to attempt Sharpening these as that would affect resale especially since I don't have a lot of experience sharpening . I'm looking for Recommendations on a Factory Knife that would fit my large hand ( maybe a drop point design , maybe not ) and be close to shaving hand hair sharp . Also as to where to buy it . TIA .
