I am giving this little unit top marks. I think it has everything any person would need, who wants to sharpen knives (and tools) on a stone. The two diamond grades are a good choice. Course for reshaping an edge (like taking a kitchen knife from an undetermined edge-angle near 20ยฐ to a solid, known 17ยฐ angle (good for lots of kitchen knives, except some Japanese styles which like a 14ยฐ or 15ยฐ edge.) The 'fine' diamond face of this block is very fast cutting, and will sharpen most edges in a few careful passes, if they're near-sharp. The ceramic face works so well at finishing, it's surprising how keen my knives were without stropping. My favorite part of the set is the little edge guide. It is of better Design than the similar one I use. I recommend that each user uses this pretty universally. It's low profile gives a very good read on the sought-after angle. I won't complain, or give marks off because I quietly felt the unit could be a little heavier. It works really well. It's non slip feet are pretty good, and it profits evn more from a little piece of non slip mat, if you have it. All in all very good. Competes well with the 2 sided Sharpal diamond stobe also sold on Amazon (currently for 2 very different prices). Of the 2 I'd choose the Sharpal, and would have a couple other gadgets (a very fine water stone, or some adhesive diamond paper, a leather strop, and compound, etc.) But I think a lot of people will like this unit. And I think they should.
