The Wooden Sword is a wooden training sword. Its move list resembles that of the Dragon Sword, but it can only strike, cannot perform Essence/Ultimate Techniques, and cannot decapitate, in addition to lacking several other moves of the Dragon Sword. This weapon can be upgraded 7 times.
When fully upgraded, the Wooden Sword's visual appearance changes to resemble an eku (an oar used for combat in Okinawan Kobudo) called Unlabored Flawlessness. The Unlabored Flawlessness has a unique ability to it; when the user is at low health (under 25% health), the characters imprinted on the back of the weapon begin to glow, signifying an increase in the weapon's power. The lower the character's health, the more powerful the weapon becomes. Damage is increased by 150% when the user is just under 25% health. Damage is increased by 200% when the user has the least amount of health possible. When the character is low in health, the Unlabored Flawlessness does the most damage out of any weapon in the game.
The Wooden sword can be bought from Muramasa at any point in the original Ninja Gaiden game and in all versions of the original Ninja Gaiden. The Unlabored Flawlessness is obtained by fully upgrading the wooden sword.

- Has the most upgrade slots from any weapon in any game.
- Although the Wooden sword is the weakest weapon, it turns into (potentially) the strongest weapon.
- The Unlabored Flawlessness deals massive knockback to smaller enemies.
- In the right hands, the Unlabored Flawlessness, using its low-health trick, can act as a game-breaker, rendering almost all challenging enemies in the game useless. This technique requires the user to be incredibly good at blocking and dodging because one slip-up can mean death for Ryu.
- It is the only heavy weapon to be capable of performing aerial attacks/Izuna drop in the original Ninja Gaiden and its remakes.
- A possible, though unlikely, precursor for the Enma's Fang (aerial attacks/Izuna drop combined with heavy ground attacks).
- The Kanji on the Unlabored Flawlessness reads 天衣無縫 or "Ten I Mu Hou", which when translated essentially means "Perfect beauty with no trace of artifice", or simply, "Flawless".
- When fully upgraded it is a reference to Miyamoto Musashi's famous duel where he used a bokken (wooden sword) carved out of a boat oar against Sasaki Kojirō.
- In the Fallout: New Vegas add-on Gun Runners' Arsenal, one of the added weapons is a katana, whose special attack references the Unlabored Flawlessness.
