The easiest way to do it would be thus:

• Add the blade weapon as its own thing in the weapon tab, based on whatever weapon is closest to it, tweaking as needed.
• Add that weapon to a character like any other just to make sure it looks right; damage dice, attack modifiers, etc.
• Once you're satisfied with the weapon, add the Helper.Helper tag to it in the Editor. This will tell Hero Lab to make it NOT chooseable like a sword or spear, essentially hiding it from someone picking it from the in-game weapon menu.
• Then on the shield in the editor, click the Bootstraps button and add the weapon to that.
• Now when the shield is chosen, the weapon should automatically be added to the hero as well.
