Where ave these been all my life?!?!?!?! Bought this set (LINK) from Amazon for $46.99 delivered (with Prime). They arrived yesterday and I did a couple of tests with them. Did a Mora Black that I loaned to a friend who tried to sharpen it without knowing what a scandi grind is and put a secondary bevel on it. Used these stones to correct the bevel back to a true scandi and they worked extremely well!! Had an old beater knife that a very bad convex bevel. Used these to take it back to a traditional cutting bevel and again they worked extremely well. Tried to touch up a Opinel on them and well.... need to work on my technique on this knife. Since the blade is already super thin which makes the bevel really thin, I have to work on getting the angle right. No slam on the stones, this one was just me. Tried in on my Buck Mesa and another success. Most of you know that I kinda suck at sharpening to begin with. But using waterstones and being able to go back and forth across the stones helps me to keep the same angle on the blade. When using a traditional stone, every time I lift the knife off the stone and bring it back to the stone for the next push, I wold always get a different angle. Being able to go back and forth on the water stone, it is so much easier to keep the same angle on the blade. Only down side is trying to figure out how to keep the slurry that builds up off the handle of the knife. I have an idea that I am going to try later on today. I'll let y'all know it it was a success or not. I have never used the more expensive stones so I can't give a comparison with regards to quality and such. But these are well worth the money in my book! Even though the wife keeps giving my crap for buying "rocks"!!!
