Any bladed, edged uh, implement needs to be sharpened on a somewhat regular basis. If you do happen to actually have a real live blade um, it's important to begin the study of how to keep the blade sharp and properly tuned. Um, it is a sensitive instrument. There are different types of stones involved, and an entire routine that needs to be implemented when you're caring for a sword. You have to uh, rub the stone against the blade in order to actually sharpen. If you're caring for the practice sword, um wiping it down and oiling it um, with a fine oil on just a regular basis is a good way to keep it in good condition and serving you for your training needs for many years to come.
