… shield and buckler? … do you mean sword and buckler? Bucklers are shields (small versions of them).
Outside of the specific designs, I’m pretty sure the Toa’s weapons are basically final.
- Tahu - Greatsword
- Kopaka - Sword or Spear and Shield
- Gali - Hooks
- Onua - Hammer
- Pohatu - Staff with a mace on one end and flail on the other
- Lewa - Dual Axes with Tonfa-like handles
