I realize this review is for the Blue Sapphire stone only, but I'd rather review the Lansky System all together. This particular stone came to me and the glue had let go from the holder. I didn't get butt hurt over it which is the fashion these days, but rather glued it back together and used it, hence the 4 star rating. I had been working with metal and in metal fabrication for 40+ years and had never made a knife largely because I could never seem to get them sharp. I always admired people who could drag a blade across a concrete block then shave with it, but I figured it was just my own limitation. I saw a knife maker on Youtube who recommended the Lansky system and it was really quite affordable so I gave it a try. It's simple to use and from the start, I got good results. I wish I had discovered it sooner. The only thing is that I tried to cheap out and get the basic kit and should have gone ahead and got the larger kit with all the stones, Blue Sapphire stone included. Live and learn. When using the simple guide, the stones will polish the blade edge making it amazingly sharp. So don't be a cheap bastard like me, but rather spring for the whole set. You'll love it and no more dull knives. Read full review

I have used various Lansky sharpening products since 1985. This is a very nice addition to my Lansky Deluxe sharpening kit. it provides a very smooth polish to the beveled edge that renders an even sharper blade.

Very useful on sharp blades to get a mirror shine on the cutting edge. Razor blade sharp, is easily attained with this stone.
