CollisionShape position

Troubleshooting physics

Is there any way i can position the collision shape to the sword? i havent found a way.

This is the code i use for creating the sword

Node swordModel = (Node) assetManager.loadModel("Models/sverd/Sphere.mesh.xml");
        swordModel.scale(0.25f);
        swordModel.rotate(0,0,1.3f);
        Weapon sword = new Weapon(swordModel);
        rhandNode.attachChild(sword);
           
        GhostControl weaponControl = new GhostControl(new BoxCollisionShape(new Vector3f(0.5f,0.02f,0.02f)));
        sword.addControl(weaponControl);
        bulletAppState.getPhysicsSpace().add(weaponControl);
