I went to try out some knives today and decided on a Santoku. The two I liked best are the MAC Pro 6 1/2" Santoku w/ dimples and the MAC Damascus 7" Santoku. I like the handle on the Damascus a little better, but it's $100 more. I'm wondering if there is a big difference with the performance of the blades? Is the Damascus blade better (stronger, stay sharp longer, etc.) or just prettier?
