I'm new to sharpening so I need something that will allow me to set up the blade quickly so I don't have to hold the angle for too long. The 220 was great at it and I was able to fix a small chip on two of my knives pretty well. A few dozen passes over 1000 grit and a honing knife and all was fine. The 220 wore out very quickly and there was a lot of dirt to wash off but like I said I'm a beginner so I don't know if this is common or not. In any case, everything worked without any problems. The plastic case is also good and offers some protection during storage.
