A patina that is aquired without time as a major ingredient doesn't look quite right.It looks as artificial as it is,but a carbon steel blade that has been used for years,field dressed and skinned critters,peeled apples,oranges,and potatoes,sliced tomatos,etc,is a beautiful sight to my eyes.I tried all them other methods on a Randall Model 26 with an O-1 blade but it looked as bogus as Pamela Anderson's......lips.I crocus clothed it back to shiny,and now cut anything in the kitchen that needs it,it slices a lot of onions and tomatos,trims fat off of stew meat,slices bacon,and stuff like that.It has gutted and skinned one deer,gutted several trout,and will likely clean another deer before the month is out,and it is starting to get "the look".It has a long way to go before it looks like my old Case stockman,or my old Schrade folding hunter,but to me thats sort of part of the deal,but heck its your knife,have at it any way you want.
