I have had difficulty putting a 13° primary bevel on some narrow blades such as that of the Chaparral. There is insufficient clearance, causing the diamond stone to hit the folded segment of the jaw-holding plate. I am using the "new" low profile standard jaw. I like a secondary bevel of 15° using the Sharpmaker, so my choice of primary bevel permits this.
Would the pen knife jaw enable the low angle I like? It seems that the same clearance problem would apply.
