I've had mine for years with no problems. I'm extremely skeptical of people claiming to be expert chefs and running into chipping problems. That should never happen if you're using and maintaining the blade correctly. Even then, Shun offers a lifetime sharpening and maintenance guarantee if you somehow screw it up.
omgjjdIf you have had it for years it may not be VG 10. My buddy has an older one that has a different steel, no chipping issues. I have the newer VG 10, and I do get quite a few chips. I greatly prefer my global chef to my shun classic chef. The shun is prettier but the global is a work horse.
I am not an expert chef. I am a knife nerd who enjoys sharpening.
