After reading a sharpening blog (no ref allowed) i have started to wonder if my 1k is redundant for most razor honing purposes. If a 4k shapton glass can cut almost, if not faster then a Chosera 1k, what is the point of the 1k?
The Chosera 1k is reported to remove 9 Micrograms/stroke at 500g of pressure, while the shapton 4000 removes 11 Micrograms/stroke at the same pressure. At 2500g of pressure the Chosera cuts marginally faster (44 vs 41 micron/stroke).
This pressure is really not relevant for razor honing, but it should at least show a trend.
The test piece that was used is hardened carbon steel. The hardness was not mentioned.
4k striations is much easier to remove then 1k striations. Going by shapton's recommended grit jumps i would only need a 3-4 k and a 10k + finishing stone. An 8k in the middle would probably be nice to have, followed by some sort of natural stone if you want to skip the higher end synth.
It seems like allot of people are starting a 1k level to "reset" the bevel.
What am i missing here in the argument?
The 2k shapton also cuts at almost the same rate as the 4k. I do not have the 4k, but i am starting to think i need reset my starting point.
I do have the 2k and the 3k shapton glass. I am not able to tell if there is any difference in the cutting speed between these stones.
My Naniwa pro 3k also seem to cut really fast. So unless you are taking out major chips or doing heavier restorations, and even then, do you need a 1k stone?
The 1k Naniwa pro seems to be really popular.
