No offense, but your knife guy being a professional, that cannot come as a surprise.
I have had two different set of knives sharpened 'professionally' (that is, I paid for the service) several times at different places including a high end cutlery shop, a kitchen store and an independent. They all left me dissatisfied, if not absolutely furious.
I use the Lansky System to sharpen my knives and, frankly, if that means I have to replace them sooner, that's the price I pay for sharp knives.
