Honing technique issue 95% likely. Are you really dominant with one hand as opposed to the other? The difference in pressure can be imperceptible to the honer. It helps overall if you start doing things with both hands just in the course of life itself. If you're a righty, deliberately start using your left hand. Let it feel more, coordinate more, be more delierate, and the biggest one - get the muscle memory of honing into the less dominant hand.
