Aloha michdad,
Glad you are enjoying the SubClaw...seems like everyone is, and I am very happy about that!:thumbup: However...
I commend your learning on bench stones...not easy by any means. (For me anyway.

) However, I freehand 99% of the time, using my Spyderco Pro-File set, or I just whip out the Triangle stones from my Sharpmaker. Anyway, one of my friends in Europe had no access to such luxuries BUT he did have a fine or extra fine bench stone. Here is one of my "old tricks":
Hold the bench stone on a surface that will
not enable it to slip, since you will be angling the stone on one of it's ends. Now, ya know the corners of the stone? Run your knife along the corner as you would with the Sharpmaker. I have successfully touched up SE and PE, as well as Hawkbill blades in this manner. Sometimes when doing yardwork, I am too lazy to run into the house for my Pro-File or Sharpmaker...so I zap the fine stone with some water, or WD40, and away I go!

I hope you could "visualize this"...the key though, as with all sharpening is maintaining that angle, as you very well know.
Keep us posted and God bless!
