Need to upgrade my main skinning knife. I've been researching and have narrowed it down to three knives. The Kershaw Echo with a orange handle (comes with a zipper too, but don't see myself packing it) for a little over $30. A Knives of Alaska Alpha Wolf D2 steel, or a Knives of Alaska Alpha Wolf S30V steel. I've heard good things about the Echo and it is less than half the price of the S30V Alpha Wolf, but have read some tests that show AUS 8 steel will loose it's sharpness in half the time of the D2 or S30V. The S30V is the most expensive at around $90, but has some good reviews. Negatives I've heard are quality control of the steel and microscopic chipping when it gets sharpened, thus diminishing it's sharpness. D2 is tried and true, but not as corrosion resistant as either of them. Real world experience or correction on my findings are much appreciated.
