So I was going to buy my father the Ken Onion 8" Shun chef's knife. I went to The store and saw the Calphalon Katana 8" chef's knife, it was labled "VG steel" so I thought it was also a vg 10 core like the Shun and bought the knife. Turns out that the Katana is actually vg-1 steel not vg-10. I am not familiar with vg-1, other then CS uses it, and don't have any knives in this steel. My question is do you guys think that the Katana I bought will be on par with the Shun? or should I unwrap it return it and go buy the Shun. Only one more day to deside, HELP!!!!
