Collecting swords and other edged weapons is popular among hobbyists. But over time, any sword's edge will begin getting dull and require a sharpening. This seems like an intimidating job, but it just takes some practice. With a metal file, a sharpening stone, and some oil, you can keep your blade looking like new. However, it you don't have any experience with sharpen the blade, we don't recommend our customer to sharpen the blade by self. You may hurt yourself. Please bring the sword to your local store to do so.
