How to Care for Your Thaitsuki Nihonto Sword

The first thing that you should always do after you are done using your Thaitsuki Nihonto katana is to place it in its scabbard or saya. Your scabbard was made to protect your blade from long exposure to air, which can corrode it. You should also know that your scabbard helps to keep your blade from reshaping. Yet, if none of the reasons above are convincing enough to you, you should put your katana in its scabbard as a safety precaution. If nothing else, leaving a blade out in the open after use could cause a very preventable injury to occur. If you did not already know that samurai swords are very dangerous weapons that can easily injure or kill someone if they are not handled properly, you should research how deadly they can be if they are not handled properly. Do the right thing, and just put away your blade after you are done using it for not only your safety, but the safety of your family and others.

Aside from safety, one of things that you will want to avoid as much as possible is touching your Thaitsuki Nihonto blade frequently. If you did not know already, your hands produce oils that could ruin your blade if it frequently touched. So, do not touch your blade unless it is absolutely necessary to do so. You should try to keep your hand-to-blade contact to a minimum, and when you do touch it, clean it with oil afterward. You can use a natural or synthetic oil to clean your blade. Some natural oils that you could use include mineral, clove, and camellia. When it comes to synthetics, silicone oil in a spray bottle will do the job.  Remember to oil your Thaitsuki Nihonto blade once a month to keep it in good and working condition.

Now that you understand the basics of how to care for your Thaitsuki Nihonto katana, you should know some ways that you can damage or break it if you are not careful. First of all, do not try to cut any object that is extremely hard or difficult to cut. Thus, you should not try to cut down large tree trunks or branches with your Thaitsuki Nihonto blade. Your sword was not designed to handle these types of cutting tasks. If you want to cut down some large trees, use an axe instead. You can practice your cutting abilities on bamboo, tameshigiri and makiwara, which is what your blade was designed to cut.

Displaying Your Sword and Sharpening the Blade

If you decide to display your Thaitsuki Nihonto samurai sword over a horizontal stand, make sure that the edge of your blade is facing up. This is very important, because doing so will prevent your blade from becoming damaged inside its scabbard. Yet, when it comes to deciding which direction to display your sword’s handle, this decision is up to you. This choice is more of a matter of preference rather than correctness, so do what you like best.

When it comes to sharpening your Thaitsuki Nihonto samurai sword, leave this task to a professional. If you do some research, you should be able to find a professional in your area who is certified and knows how to sharpen your Thaitsuki Nihonto blade properly. You should seek a professional when you think your blade can no longer perform basic cutting tasks.

Final Thoughts

It is important to reiterate the fact that your Thaitsuki Nihonto samurai sword is a very dangerous weapon. Thus, you should know how to handle your sword responsibly to prevent an unexpected severe injury or even death from occurring. It is also important to note that you should definitely do your research before buying your Thaitsuki Nihonto samurai sword. By doing your research, you will give yourself a sense of peace of mind that you bought your sword from a vendor that you can trust. Finally, make sure that you keep up with the maintenance of your blade in order to make it last a lifetime.
