Do you hone paring knives?
Yes, you should hone your paring knives.  The technique is much the same, except that paring knives are smaller.

Since physical skills are hard to describe in text, and you have already had in-person coaching,  won't try to describe the technique; just use the one that you are most comfortable with.

Note that some santukus may have a different bevel angle than a paring knife, but given that honing is about straightening the microscopic burrs, not about sharpening or removing metal, this tends not to matter very much.
