Support BladeForums! Paid memberships don't see ads! Hello everyone, I have a Case Sodbuster CV that I have owned for many years. My primary question regards the sharpening of the knife. I am currently using one of those cheap pull through sharpeners that supposedly chew up steel and ruin the knife. However, my knife slices paper and shaves arm hair, so I feel it's doing ok. I want my knife to last forever so I worry that the pull through sharpener is not the best option for longevity, but I am terrible at stone sharpening and feel that may be a worse option. Am I overthinking it?
