This is an update to a review I placed here 5 years ago. These blades are still a good bargain but I just learned that they cannot be re-sharpened. I sent them to Burn's Tool sharpening service and they responded that the blades were "disposable, and will not sharpen nicely". BUT it took me 5 years to dull 1 1/2 sets of knives (3 edges), so I am not terribly disappointed. If anyone knows somewhere that will sharpen these knives, (at a cost less that just buying new ones), please leave comment here.
