Does anyone have some tutorials/ tips on making weapons.
I tried to make a sword but I failed a little.

Here’s what I would do:

  1. Start by scaling the default cube’s Z Axis until the cube is as thick as you want your sword.
  2. Adjust the width of the sword to whatever you want.
  3. Select one full side of the cube and extrude it out several times holding the ctrl key to snap the extruded portions to the grid.
  4. Then extrude 3 or 4 more times, but make them closer together than your last ones.
  5. Shape the final extruded portions of your sword by scaling them down into a point at the end.
  6. For the handle I would start out with a cylinder, extude it a a few times, turn on subsurf and then shape it to your liking.

Not very detailed I know, but I hope it helps.

Here is a nice sword tutorial, right in the Blender documentation:
