I'm also a big fan of Gene Ingram knives, and often carry an SLK or Naked Pocket knife.

I find that for slicing, the long cutting edge of a big belly offsets the shorter blade quite nicely. It requires only minimal adjustment to your motor skills.

Purely armchair b.s. but they say it takes 4 inches to reach vital organs in a thrust. So, if you're practicing to use the 2-inch blade defensively, you'd want to emphasize slashes.

Finally, you might investigate keeping a longer, serrated, plastic-handled, obviously kitchen knife knife at your desk for cutting fruit or cake that won't succumb to your 2-inch blade.
