I guess it depends on what you cut when you are skinning and de-boning. I can clean several deer without needing any time on the stones - I do touch up all my blades on ceramic sticks once cleaned after skinning/cutting up a deer (around here 100-125 lbs. is typical "meat deer", 200 lbs. is a monster). My stainless steel Bucks include various models made with 440C, 425M, and 420HC. OH
