I've never sharpened the blades you have pictured, but I've yet to meet an auger blade I cant sharpen.
No way would I let the saw filers at my mill touch them. They excel at putting tension back in saw blades, soldering teeth back on, and sharpening knives on jigs that should more or less be idiot proof. But their attempts to sharpen barker tips on a home made jig have me convinced they don't understand a thing about maintaining the correct angles.
With auger blades it is very important that you maintain the original angles. Carefully take off metal from the bevel side (usually the top) with a high quality file in good condition, when you are pushing a burr on the bottom, lightly take it off without removing too much metal, you should be good.
As with any sort of cutting tools, regular touch ups are a lot more easy than trying to bring them back once they are really dull. I've been running the same blades on my hand augers since the mid 90's, and the ones on my current power auger are over a decade old, I touch them up every season or two and they have continued to cut fine.
