The Razor Sword is obtained by upgrading the Kokiri Sword at the Mountain Smithy for 100 Rupees.[1]Link must leave his Kokiri Sword at the smithy for an entire day before the Sword is ready. Once completed, the Razor Sword features a double blade with increased range and double the strength. However, its edge will dull after one hundred strikes and become the Kokiri Sword once again.[2][3]
Playing the "Song of Time" to go back to the First Day will revert the Razor Sword back to the Kokiri Sword. However, the Razor Sword can be further upgraded to the Gilded Sword, which will not revert back to the Kokiri Sword.

In SoulCalibur II, the Razor Sword is one of Link's weapons. Paired with the Hylian Shield, the Razor Sword can be bought in the Regulus Shop for 600 Gold while playing the Weapon Master Mode. When Link equips the Razor Sword, his attack goes up to 125% while his defense stays the same. However, due to the Sword's short reach, Link will take 15% block damage compared to the usual 10%.[4]

600 Gold
Attack goes up 25%
Short reach
Takes 15% block damage
A sword forged by the blacksmith from the Mountain Village on Snowhead. The blacksmith is famous for his perfectionism--this sword is yet another excellent example of his craftsmanship and boasts an amazingly sharp cutting edge. Unfortunately, the metal used to forge this blade is prone to chipping, so there remains some concern about its defensive capabilities.
Trivia
The blades of the Razor Sword resemble the rightmost strokes of the kanji 剣Ken, meaning "Sword". Whether or not this was intentional is unknown.
↑All right... To reforge your sword, it will cost you 100 Rupees. It'll be ready at sunrise. You'll have to let us hold onto your sword until then. Keep in mind that after you use your reforged sword 100 times, it will lose its edge and it'll be back to its original sharpness... — Zubora (Majora's Mask)
↑Your Kokiri Sword has been strengthened and forged into a Razor Sword! This new, sharper blade is a cut above the rest. Use it up to 100 times without dulling its superior edge! — N/A (Majora's Mask)
↑The Kokiri Sword you went to the trouble of sharpening is now just a plain sword again. Take it back to the swordsmith to reforge it. — N/A (Majora's Mask)
↑Good offense offset by a short reach and a penetrable guard. — N/A (SoulCalibur II)
