same thing happened to me, i purchased a razor that was shave ready, i tried it on my stomach and it some smooth. then i stropped it and tried it on my face, and i had the same experience as the op. i couldnt shade i put it down after one drag. turns out i ruined the edge with poor stropping skills. then i got another razor from a professional honer and he sent it to me honed and stropped. i shaved with that and it was amazing.
