Does the serrated portion of this knife resharpen, easily? This knife appears to be very well-made and for the price of $29.95 at a local big-box-store, it is probably one of the better deals "out-there." I have had zero-experience with serrated knives and would prefer the non-serrated version of this knife but unfortunately, the store does not stock that model. What are your thoughts/experiences, relative to this knife? Thanks, in advance, for your input.
