I am buying my son a knife for Christmas and need some help. I do understand buying knives are a personal thing and should be held and looked at by that person, but just want to get him started with one. He is a at home cook, and loves to cook. I am looking at getting him the Mac Pro knife MBK 8.5 or the Wusthof classic Ikan chefs knife 8 inch. He is left handed, but I have no idea which hand he uses a knife with. So my question is , can the above knives be used with either hand? Any other comments or feedback would be great too. Thank you!
