A drunk friend took my Global chef knife during a party and tried to hack a coconut open. The multiple blows made the blade edge suffer some minor dimpling and waving. The damage occurred right in the cutting sweet spot about 1/3 of the way down from the handle and, despite that the damage appears minor, it has a major affect on cutting quality.
Is there any way for me to salvage the knife? Without the benefit of grinders or even a whetstones, is there something I can do or some place that I can take the knife to get it repaired? (I just use metal and ceramic sharpening rods.)
