In general, it's very easy to paint the blade with a silver spray can. Before that, you need to cover the places where you don't want the paint to go with masking tape or a plastic bag. It's better to do it in three layers, it looks more beautiful and realistic. I liked the gold color, it looks great. The tsuba (guard) should also be gold for a perfect match. The handle should ideally be made of leather for aesthetics, and it will be 🔥🔥🔥.
