I imagine it might take awhile before I get the sharpening of the knives down. I am just hoping to make our kitchen knives sharper. If I had to send out our knives to be sharpened, it would not take very long to just buy some new, sharp, knives. The labor rate for sharpening stuff is too expensive unless maybe you had a very expensive knife.
Speaking of sharpening costs, I had a few wood chipping "knives" that I wanted to get sharpened. Doing my due diligence, I got a price quote up front. Then I sent them into the shop to be sharpened, waited a few weeks, and they came back to the store. I went to pick them up but the price to sharpen them was 4X more than what I agree to. I complained to the store manager, showed him the price quote I had agreed to, and showed him that I could buy brand new wood chipper "knives" for less than the sharpening service!
Long story short, manage let me take the wood chipper "knives" no charge. He said he would talk to their service guy who does the sharpening and let him know that you can't accept a job at one price and then charge 4X as much for the service - especially when the sharpening service is more expensive than buying new blades.
I never went back there for sharpening service. I just shapended the wood chipper blades as best I could at home. I am hoping that my new 1 X 20 bench sander will sharpen up my wood chipper blades because they get dull in only a few hours. I could really save some money on those blades if I can sharpen them myself.
