Got the set today, and I really like them so far.
The stones are larger than I thought they would be, which I'm perfectly happy about.
The 120 grit stone is indeed very coarse. The 1000 grit stone does, however, cut surprisingly quickly. I haven't had a problem going straight from the 120 to the 1000 grit, though something in between might eventually make a nice addition.
The 3000 grit stone leaves what I would call a 'near mirror' finish. I can see myself in the edge, but it's just a little bit hazy.
I got a similar finish from the gatco 'ultimate finishing hone' (1200 grit ceramic) but the waterstone works so much faster, there is really no comparison.
The whole process is much different than the gatco system. I definitely need more practice before I get a perfect edge. Right now the bevels I'm getting are slightly convex.
One other thing I've noticed is that if I'm having trouble sharpening freehand, it's much less frustrating than when things go wrong with the gatco system. Mistakes made freehand are
my fault, and something I can learn from. When things go wrong with the gatco kit, however, it's usually because the clamp doesn't work well on flat ground blades, or the blade is too small for the clamp, or the rods are bent, etc.
It's a learning process instead of a battle.
Coming from the gatco system, there's a few other things I've noticed. For one, waterstones are messy, and get water everywhere. Water, on the other hand, is much easier to clean up than oil. Also, the water stones don't 'fill up' and have to be cleaned like the others do. Just a splash of water and a little rub and they're good.
The only real difficulty is maintaining a consistent angle, which I'm working on. And even though it's not perfect, I'm still getting razor sharp edges.
