Question: Do I have to oil it?
Document: This is my first sword and so far I am very impressed with how well this sword seems to be in spite of the fact that it only cost $50. As soon as I took it out of the box I wiped off the grease and applied some oil. While applying the oil, the cloth I was using ripped in half from running along the blade.
This annoyed me a little but not enough to get upset. Maybe there are different versions of the same sword.It came heavily oiled, I recommend cleaning the oil off, especially on the blade collar so it doesn't get into and warp the saya over time. Get new oil for the blade.The saya (scabbard) is defintely wood but doesn't look like it from the outside.
Received this item the other day and was not to  impressed. It makes a nice display piece and not much else. Being a novice I do not have every part of the sword memorized so bear with me. The blade rattles in the scabord but at the same time has a nice tight fit. The blade has a nice coat of oil and is very sharp. I would not want to defend myself I would be afraid the handle would come off. But you get what you pay for.
The blade is not razor sharp but serviceable. Also bear in mind that the steel used in the blade is pretty pure, so you will likely want to purchase a kit to clean and oil the blade to prevent oxidization, especially if you plan to use it to cut targets.
This is a great sword. Fast shipping on prime. As many reviewers mentioned couple things to consider, blade has lot of oil on it so will need some cleaning. Also, blade wiggles little bit at first, but if you take out the top seppa and switch it with bottom seppa, it will make the blade more firmer, and no more made in china writing.
I highly recommend.
I highly recommend it for sword enthusiasts with average budgets.
I got it to shave the hair on my arm just like my other swords.
I thought this was just going to be an unsharpened sword that was bad but I got it and was more than satisfied
