For field dressing, it only needs to be sharp enough to cut a thin layer off of your finger nail (scrape blade at angle across your nail). If your blade feels jagged, you need to sharpen it with an extra coarse sharpener until you lose the jagged edge. Then move to sharpening with coarse, fine, extra fine. I would recommend the DMT Diafold sharpeners with blade guide. Use the blade guide on either of the sharpeners when you are using them.
