I'm a glutton for punishment. Japanese whet stones all the way, even if it means having a 3-4 knife rotation. The VG-10 chips out mainly while boning, not sharpeneing, nevertheless, I love the edge it takes. With that said, the Ken Onion version of the work sharp sharpener and the grinder attachment has caught my eye a fair number of times. $200 with a decent array of grits and strops to finish it off is very appealing with the number of knives I own. That pic doesn't include the pocket knife rotation either. PM2's in S30V, S110V, S35VN, OKC Rats in D2 and AUS-8, the list and metals go on... A sharpening system is highly appealing, but it's hard to give up the stones.@Tinkermatic The Wicked Edge system made sharpening the Shun's easy. Diamond stones FTW. I did try a more traditional method (regular stones) to sharpen the same blades and that was far more difficult. Granted, the systems are NOT cheap, but you do get what you pay for. I stay clear of anything powered for sharpening my knives. Mostly because I don't trust them to not remove too much material. IME/IMO you want to remove the bare minimum to achieve sharpness on your blades (all blades).
