11 The Killing Edge is a C-rank sword in Fire Emblem: Fortune's Weave. It is one of only six weapons in the game with a near-complete published stat line, it grants the Deadly Blade combat art, and its 40 Uses are the highest durability figure published for any weapon in the roster.

66 Curse is a stat field sitting between critical rate and range on every weapon line, and no published material explains what it governs. The Killing Edge leaves it empty, which is not the same as a zero: only one documented weapon, the sword Veroquine, carries a published Curse value at all. Weapons covers the full stat schema.

1313 Against the Iron Sword one rank below it, the Killing Edge adds 2 Might for 2 more Weight and keeps the same 90 Hit, then doubles the durability. That last figure matters more than it looks. Uses drain only when a unit performs a combat art, so 40 Uses is a budget for Deadly Blade rather than a maintenance figure, and it buys roughly twice as many arts as anything else on the sword list.

1515 Veroquine is the only sword with a higher Might, and it pays for it with 12 Weight, 60 Hit and a reported requirement of two proficiencies at once.

1717 The Zero Critical Rate
1818  
1919 Every weapon entry published for this game so far reads a critical rate of 0, and the Killing Edge is no exception. As of September 2026, no official weapon description states whether that column holds unfinished data or a real value. Nothing published for this game gives the sword a built-in critical bonus, so what it actually offers is the combat art, not a passive crit boost. Critical figures quoted for a weapon of this name anywhere else belong to other titles.

25-Combat arts are the stronger attacks that spend a weapon's Uses, while ordinary swings cost nothing. Arts can be enhanced separately using a material called the Magic Resonance Stone, looted from defeated enemies. Combat Arts covers the system and the full list of named arts, and Blaze Arts covers the separate system the four Heroes use, which spends health instead of durability.

2727 Description

2929 The English help text calls it a sharp sword crafted with eastern techniques and notes that it allows the use of the Deadly Blade combat art. The Japanese line says the same thing. That is the only origin the game attaches to the blade: no smith, region or previous owner is named for it in published material. The setting does have an eastern land, Sai, mentioned in one character profile, but nothing published connects the sword to it.

3131 Buying and Forging
3232  
33-Weapons are bought at the shopping arcade in Dagsion, where a blacksmith stall also upgrades gear already in the inventory using materials gathered out on the world map, mostly from the dungeons covered on Dungeons and Clashes. Forge levels are written as a plus and a number after the weapon name and run to at least +2. As of September 2026, no forge line has been published for the Killing Edge, and no purchase price has been shown for it either. Iron Bow is currently the only weapon with published forge figures.

37+Where to Find It
38+ 
39+The Killing Edge is a fixed chest item. One of the Part I chests in Shadowy Cave, a dungeon in the Lambath region with an ideal level of 12, holds it, and Dietrich's path passes through that cave as its story dungeon in Chapter 4. In Part III, a chest at Nowah's Cave in the Elektra region holds a Killing Edge +3.
