I have a system which works for me and that is a set of 6 inch bench jointer blades. They cost about $10.00 at your local home supply store, are six inches long, one inch wide and about 1/8 inch thick (you might want to dull the blades a bit to not nick your fingers when inserting your small knife ). Insert the small knife between the planer blades then insert the planer blades into your knife jig. This method extends the length of your jig and allows the correct angle without the jig rubbing the wheel. Adjust accordingly and, voila, you have a great "baby" knife jig. You can also use the same system to do long filet knives on your Tormek short knife jig. I can sharpen pen knives (1 1/4") blades with absolute accuracy and the time taken setting up the jig is about one minute longer than just using the Tormek jig. A bit of tweeking may be necessary on the leading edge of the planer blades to thin them out a bit. Improvise, improvise.
