Razor Sword

The Razor Sword is the first upgrade to the Kokiri Sword in.

Uses and Location
The Razor Sword is obtained by upgrading the Kokiri Sword at the Mountain Smithy for 100 Rupees. 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.

Playing the "Song of Time" to go back to the First Day will revert the Razor Sword back to the Kokiri Sword. The Sword can be further upgraded to the Gilded Sword.

Soulcalibur II
In, 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%.
