And a weapon attack when you are unarmed gives a "fear factor" which helps you learn to be calm under increasing pressure. Even a tanto tsuki elicits a much worse flinch than a bare-hand tsuki, and this lets you work on the flinching more easily.
No, no, -- by all means flinch. Natural reactions are not to be undone or overcome, but directed. Hold on to that instinctive reaction, for dear life -- your brain stem is much faster than your thinking brain.
Just turn it around. If you feel the pit of your stomach fall, then let your flinch happen, in fact, pile on -- into the direction of attack -- it's called irimi.
