there are people on SRP that only take their razor up to 8k then strop and shave, but most of us like to go beyond the 8k point to make the shave easier and more comfortable.
~the nani 12k is a good suggestion.
~but i think a barbers hone would also be great for you. they are around 8k but generally leave a smoother finish than a synthetic 8k and they were made to specifically for barbers to refresh their blades. and they are pretty cheap
~ coticles are good but very tough to learn and their prices have risen very much, i wouldnt recommend it.
plus chromium oxide paste will always kick your edge up to the next level and its cheap.
