Has there been any update on this?
Yea, I've received their third knife within a week after I posted, this time through Japan Post/EMS. I have given the third knife (
Santoku VG-10 Damascus Western Handle 170mm H) away as a present and didn't take photos, but regarding fit and finish out of the box it was the best of the 3. It was really sharp, even though you could barely see an edge, so they basically leave it up to you how you want to sharpen it. I sharpened it at a ~15° angle before I gave it away and actually didn't reach the sharpness it came out of the box, but probably it came sharpened a bit steeper, or my sharpening skills are still lacking... still got plenty sharp

The handle, while not full tang, also had a much nicer finish than the Tosa one with western style handle. The blade is also thinner. The spine of the VG-10 was already slightly rounded, but still fairly uncomfortable, so I rounded it some more.
The first two Aogami Super knives were both made in Tosa, while third VG-10 one I got was made in Echizen City in Fukui prefecture. The Tosa ones were as I said bit rougher regarding fit and finish.
I think they are, as Danzo guessed, not great, but still good. Since you can't really get any handmade knives under $100 I think their rougher fit & finish is acceptable for the price (the cracked handle obviously was not though). But since I don't have much experience with handmade knives I can't really compare them to others, so don't take my word for it.
I think you can give them a shot, but you should be willing to give them a little sandpaper treatment around choil/spine. Especially the ones made in Tosa.
PS: I also mirror-polished the one that came with the cracked handle to make it look a bit nicer. I actually kept some of the deep original grinding scratches on purpose because I liked the way it looked. The chisel engraving looks much better now, too, because it wasn't flat before.
