Boy what a discovery!! I bought some Sigma Power Ceramic stones from Stu (TFJ) and got the first installment just in time for some shop time this morning. INCREDIBLE is by the far the best descriptive to relate how much better they cut than my oil stones and my Norton water stones. These Sigmas are fantastic.
First, with two O1 chisels (Irwin, 1/2 and 3/4) I went from flattening the backs to sharpening bevels on the Norton 1000 and the Sigma 1000. The Sigma 1000 was multiple times faster!!!!! At least 3x faster. And, it left a sharper, more polished edge than the Norton. IT LEFT A LOT LESS MESS, TOO. This stone is incredibly responsive (its the Sigma hard) and very, very dish resistant. I kept drawing lines to see where it was dishing—and it wasn’t.
By the end of the morning, I concluded that oil stones produce an edge that is as sharp as the Norton 8000 but not as polished. The Norton 8000 leaves the edge less sharp than the Sigma 6000, though its polish is nearly comparable. The 13000 stone I ordered hasn’t arrived yet. I can’t wait to see what crazy sharp may look like!
When I took the Irwins, Stanley’s, Ashley Iles, and Lie Nielsons off the Sigma Power stones, I couldn’t believe how mirror polished the backs and bevels were!! Yes, I consistently get wicked sharp with Ark oil stones (ain’t no betta!!); but, the Sigma ceramics just cut and polish so much faster than the either the oil stones and the nortons. BTW, my Ark. stones cut A2, as well as the Nortons—though the Nortons are a little faster on the A2; about the same for 01. The Sigmas are screaming fast compared to that.
There is some mess. But compared to the Nortons, the Sigmas are significantly less messy in fresh dressing, water spritzing, and clean up. The Sigmas cut faster, resist dishing significantly longer, and leave the beginnings of mirror polishing much quicker—oh, and draw burr extremely faster, too.
So, I’m declaring my new Sigma ceramic stones a GLOAT!!!!!!!!
Hope this helps others on the fence, as was recently was.
