A Silver Blade is a Long Sword-class weapon Artifact available throughout the Golden Sun series. Two Silver Blades exist in the games: In the first game it is sold as an artifact at the weapon vendor in Lalivero, and in the second game it is sold as an artifact in the general vendor in Shaman Village after completing the Trial Road event and Moapa boss battle. Being a Long Sword-class weapon, the Silver Blade can be equipped on warrior-style Adepts, namely Isaac, Garet, Felix, and Piers. Its buy value is 12000 coins and its sell value is 9000 coins.

The Silver Blade increases the wielder's base Attack rating by 108 points. Its Unleash effect is Aqua Sock (it may be supposed to be "Aqua Shock"; Aqua Strike in the Japanese version), with the standard base activation rate of 35%, which is a physical attack with an additional 42 points of damage added, and then the resulting damage is either increased or decreased based on how the user's Mercury power measures against the target's Mercury resistance. Visually, Aqua Sock resembles a pillar of water shooting up from the ground at the target's feet as the user performs a physical target.

In Golden Sun, the Silver Blade is physically the strongest Artifact sold in the last town of Lalivero, but it is not necessarily a great weapon because of it, especially considering its Mercury-based Unleash will not get an easy boost from the elemental affinities of your warrior Adepts unless you arrange Mercury Djinn so either Isaac is in the Guardian class or Garet is in the Luminier Class, and it does not have any extra side effect. Most players buy it anyway, but mainly as a placeholder for the Gaia Blade that can be found later in Venus Lighthouse, as well as perhaps the Muramasa near the end of the optional Crossbone Isle.

In Golden Sun: The Lost Age, the Silver Blade is available as an Artifact quite late, at a point where the party can have weapons equipped that are almost literally one-and-a-half-times as strong as a Silver Blade (Hestia Blades at Lemuria's Lucky Medal Spring, for example). It will be inevitably outclassed in every regard at this point in time.
