Tetsu wakizashi

A tetsu wakizashi is an off-hand melee weapon made in the Player-owned ports minigame. It is the off-hand counterpart to the tetsu katana. It can be made in a port workshop using 50 plate, 25 pearls and 1 tengu tsuba, requiring 92 Smithing (non-boostable) and all four parts of the "tetsu swords" eastern scroll. Making one grants 15,000 Smithing and 2,500 Crafting experience.

The tetsu wakizashi will, like ports weapons and tier 90 weapons, degrade after 10 hours of combat. It can be fixed with at NPCs such as Bob in Lumbridge, or at an armour stand in a Player-owned house. If lost in the Wilderness, it will be converted to 1,250,000 coins.

Currently, a full repair costs:
 * Bob
 * Armour repair stand (at 99 Smithing with a Smithing cape)

Trivia

 * 'Wakizashi' (脇差) means 'short sword' in Japanese.
 * The primary usage of wakizashi in the real world is slashing, not stabbing.
