I ordered this stone from seller "realskuller" through Etsy on February 12th, it was delivered on March 15th. https://www.etsy.com/transaction/1582190265 I checked it for flatness, ground out some marks left on it by whoever flattened it (only one side came looking more or less ready to go, see pictures). Then I used it to sharpen my 35 year old Henckels 4 star chef knife, the only kitchen knife on hand which really could have used a touch up. Initial impression: Much more satisfactory than the Mexican sandstone I recently tried. Especially for the price. I'm going to be using this one on annything that comes up for a while, hoping to confirm this. --------- It was very well packed, multiple layers of bubble wrap, styrofoam, packing tape, yet more cosed cell foam and tape. No cardboard. If the slow boat from China had sunk, this package would have floated. The "good side". I drew some pencel lines on it, ran it over a sheet of 80 grit wet sandpaper and the lines all disappeared within seconds. Pretty flat as it came, but some scratches were present. Ran it over a sheet of 220 grit wet sandpaper for about a minute, scratches were erased. A yellowish mud was generated in large quantities- The mud quickly turned a dark grey/green when I started to sharpen the Henckel. This stone cuts a little slower than my 500 Shapton glass, leaves finer scratches. I apexed the blade, then did a slight secondary bevel. Followed that with 5 passes per side on denim impregnated with Turtle wax scratch & swirl remover using only the weight of the knife. Then another 5 passes per side stropping on bare leather... Knife sliced copier paper with aplomb. Shaved my arm. I spent VERY little time to achieve this, blade was not "dull as a hoe" before, but was not slicing tomatoes with zero pressure, occasionally glanced off the dry outer skin of big sweet yellow onions, it was far from perfect if you're a knife nerd. I'm going to go out and buy some tomatoes, also thawing out a big chunk of venison for some real world testing.
