How is it that you still don't know how to sharpen a knife even after the last one. Pull-through sharpeners aren't the best but, I guarantee that if you had used it properly instead of making a stupid time trial, the pull-through would have either won or, at least been equal. I get that tumbler is a nice sharpener but it's not the best sharpener in the world. It's just the fastest. If you're willing to put more effort into it (as most knife enthusiasts are) then, a whetstone is clearly the best for getting razor-sharp results.
