Pros: Durability, Ease of Use, Effectiveness, Overall Quality
Good solid basic stone
Great stone to get a good working edge on your knives. I've used this to sharpen dull knives in 1095, VG-10, and S30V steels, and it cuts them well. Gets a good toothy edge that can slice newsprint if you know what you're doing. I use this before moving on to finer Spyderco ceramic stones. I was initially skeptical about this stone, seeing as how it's made in Mexico, but after comparing it to my grandfather's Norton IB8 (Made in the US of A), I can say that it's equal in quality. Make sure to put oil on the stone before your sharpen and after you sharpen, then dab it off to keep the stone from clogging.
