I have an older Moki pocket knife (distributed by Spyderco in the 80's) and wish to change the serrated edge to a plain edge. I just can't get it sharp enough to do detail work and think it will be easier to maintain a plain edge. Please let me know if this is possible and what it would entail. Also, feel free to try to talk me out of my decision!! I would love a Spyderco H1 with a plain edge but hear that it does not hold an edge well. Like that it does not rust though!!
