I just received my new chosera 1k in the mail. I lapped it flat and went to honing a razor that has been gong me trouble for about a month. This one razor I have been having a lot of trouble getting the bevel set just using my 4k. As soon as I would think that I would have the bevel I would find out that I wasn't quite there yet. Boy, I don't regret the purchase one bit. It was smooth. So smooth that I was wondering if it was cutting at all. I wasn't getting much swarf, but the edge did not lie. A few strokes on the new 1k and I was shaving arm hair and feeling a tickling on the TPT. I went through my normal progression and after stropping I got the smoothest test shave I have ever gotten on this one particular razor. I can't wait till my honing technique gets better so that I can really experience the best possible shave. Getting the chosera 1k was a real step in the right direction for me to get that blasted bevel set.
