Want to get the hubby an upgraded chef's knife for Xmas. We currenly have a so-so quality 8" Wustof from about 15 yrs ago that has got quite a few nicks and is staying sharp for less and less time. I would like something in the $100 range and not sure if I should stick to traditional chef's knife or go for Santuko type. What else should I look for? I'd like this one to last 30 years - we take pretty good care of them (use a sharpening stick, keep the blade in a molded plastic cover, hand wash and dry etc), but use it A LOT.
