I received these knives and they seems Great!   They look and feel sharp and I know I can get great use of them.   My only question is do they need to be sharpened at any time.  There is no information on that.  Right now being new they don't need to be sharpened but I am wondering about future need for sharpening.  Do I need to use the regular sharpening tools or what.  I will update when I have any kind of issues.  Right now their Great!
