Answer:

Well I looked it up, the website is in my source. This is just the what you need part for the rest of the information check the website.

What You Need

Nuguigami: Wiping Paper for Sword Made of a soft, sensitive pulp tissue Made exclusively for wiping your sword. Wipes off the excessive oil and unnecessary dust. Common substitutes are soft paper towels or tissue paper (don't use those with scents or lotion).

Wiping cloth: A flannel cloth, old towel, or hand-cloth can be used for quick cleaning to wipe debris and residue from the blade after tameshigiri or handling. This cloth can be reused multiple times. Nuguigami, paper towels, or tissue paper (don't use those with scents or lotion) can also be used, but should not be reused.

Choji Oil: A superb rust preventive oil. This is not clove oil which will cause your blade to rust. Common substitute is camelia or mineral oil.

Oiling Cloth: Flanel cloth in a storage case used to apply a coating of choji oil to the blade. This cloth can be reused multiple times. Nuguigami, paper towels, or tissue paper (don't use those with scents or lotion) can also be used, but should not be reused.

Uchiko Ball: Finely ground stone powder (hazuya and jizuya) in a silk ball.
