It’s funny that Osric describes the hit as palpable – with its sense of touch, its tactile sense. I don’t THINK the hit is judged with touch. It is almost always reckoned by the eye in this scene. Though suddenly, I am very interested in Osric investigating the hit with his hands. To see him palpate Laertes wheresoever Hamlet hit would be a) possibly hilarious b) homoerotic c) a bit of surreal staging.
It might be that the hit causes a tear in clothing so it could, in fact, be palpable in a literal sense – not just a figurative one.
