Wonderful feel, good deal.
I have several other water stones and sharpeners, mostly in lower grits, and feel that these are some of the best available. At comparable ratings the feel of the 400 or 1000 these Kramer stones is far better than any natural stone I have used. I expect the biggest competitor to these would be shapton glass.
These have done great work on my Spyderco MBS-26 steel knives and masakuge VG-10. Victorinox steel sharpens in about half the time and takes an edge easily. The 5000 grit stone is a pleasure to use. I will buy more kramer and chosera
products, definitely the 10k stone and maybe the chosera 3k.The naniwa sink bridge seems sturdier, but this one is very nicely made and fits a hotel pan well.
While very expensive, this is definitely what it took for me to feel like I was doing a better job at home than I could get from a local contract sharpener. If you pay attention to the burr as Kramer says, and don't follow any superstitions, I think anyone can sharpen well with practice. 5k-10k grit on stones this nice is a whole world sharper than the edge that a single belt on power grinder can achieve. You will understand stropping once you start to take the burr off with these stones and get truly sharp.
