I have used a Case 2 blade folder (not stainless) since 1956 to gut/dress/skin several truck loads of deer, antelope, and over 25 elk, most were quartered in order to pack out. Both blades have been sharpened 100s of times and are not near as heavy as when new. The sharpening tool has been a flat, grooved steel, sold by Gerber Knives Co. I went thru a few flimsy "game saws" until I bought a commercial butcher's 12" bone saw. Works great!
I see no need to change now.
