[Star Wars] Why do the Jedi only use lightsabers?

Why do the Jedi only use light sabers in battle? Why not blasters and grenades too? We saw during the Clone Wars that the Jedi flew fighters and used the blasters on those to kill the enemy. They have often been seen reflecting blaster fire back at the enemy. I've even heard that one of the last of the Jedi once used a blaster to shoot someone in the heart in the heat of battle. It seems they have no moral issues with blasters or using blaster fire to kill an enemy. And if a Jedi just want to keep using those ancient weapons for tradition's sake, why not also back it up with a good blaster at his side?

The Jedi aren't meant to be a military order. The lightsaber is a defensive weapon that allows them immunity to blaster fire and the ability to protect another. They're not supposed to be going into war zones and fighting armies with them.
