I've been using the entry level Naniwa 1k/3k combo stone since I've started sharpening. I set bevels with a worn DMT coarse if needed. I just haven't been able to get any form of a decent edge using this stone at all. It's slow cutting and very soft. I'm pretty sure there's no burr remaining; I can't feel it or see it with the loupe. I've tried hard pressures, moderate, and really light. Tried really acute angles to slightly more obtuse (maybe within a 10-20 degree range I've tried). Deburred drawing through wood, cork, stropping on the stone, on newspaper, leather.
This is the stone (tan/red):
I can manage push cutting paper, but nothing more than that. Can't even shave hairs. Any bite that I can get on an edge goes away pretty quick too, maybe even after one short cutting session (end grain board, etc).
Do I still have a burr on there? Wire edge?
I tried out the 1k/6k from Korin a little while ago and I had none of these issues. I was able to get an edge that could pass the 3 finger and thumbnail test easily - push cut paper, shave hairs, etc. Can't seem to do that no matter what I do with this Naniwa.
