Which sounds awful fancy, I did a quick search of amazon and found it's selling for less than $60. Not as bad as I anticipated. Still, $60 for a knife is a bit.

Then I know nothing about how to sharpen knives. Back in my hometown if my knives dulled, I would take them to my dad and he would whip them into shape in no time. I should probably learn how to do it on my own.

Or just buy a new $60 knife every year or two. *shrug*
