Don't know what to tell you. I did some searches and can't find any that thin. I know one of Hibben's knives, Alaska pro hunter or something like that is listed with thin micarta liners/spacers in Red. Any reason it has to be Micarta(assuming some sort of strength issue)? Sheffields sells the 3/16" stuff, if you get desparate enough, maybe you can flat grind 1/8" off, though that's a pain to do.
