On smaller knives, I get good results using the Spyderco Sharp Maker with its ceramic stones. The two angles they are set for match up with Capt. Chris's recommendations.

Even with the stones held at a consistent angle, it still takes practice to hold the blade at a consistent angle as I draw it down the stones.

The short length of the stones makes it a bit difficult to do longer blades...I run out of stone before the full blade length can be drawn down to the bottom.

I probably need to go back to their video online to watch how they recommend sharpening longer blades.
