I'm new to the forum so please be patient while I ask dumb questions. I decided to upgrade from my old El Cheapo fillet knife, and I purchased a Knives of Alaska Steelheader. According to the manufacturers information included with the knife it was factory sharpened to a 12 to 15 degree angle. I use a Work Sharp knife sharpener and with all my other knives can put a pretty decent edge on them...BUT...it's a 20 degree edge. I'm absolutely hopeless with a stone. Even the small Knives of Alaska pull thru sharpener says it sharpens to a 18 degree angle which is not correct. When it's time to sharpen the knife will it harm the knife it gets sharpened to the 20 degree angle that the Work Sharp provides rather than at a 15 degree angle? All information and advice will be appreciated. Thank you!
