the stone were just delivered and i lapped the combo on 220 grit wet/dry on a piece of plate glass. also chamfered all the edges. there was a small chip on the 4k side. the 12k was minute chips on the vertical edges, so i chamfered them too. the combo is soaking right now. should i soak the 12k? maybe later i'll get to try and shave. got everything i need. razors, (pending a sharpening), soap, strop, band-aids. good to go.
