i'm good at making toothpicks out of knives if that tells you anything! i have 1 of what was posted by the op and use it to good success. also have a ken onion (electric) that doesn't sharpen as well. my dad was very good at sharpening knives cause we used to do a lot of castrating bulls. i'd have better luck with a de-horner (no, i actually didn't use 1 for that). there are more expensive tools to sharpen if you want to spend 1k or more.
