Note that while you can obtain duplicates of the Hylian Shield and Champion's Tunic using a combination of amiibo or the unique chest - there can only ever be one Master Sword in the world. Inside the chest you’ll find the Champion’s Tunic, Hylian Shield, and Master Sword. If you keep walking past that structure towards the cliffs, you’ll find a path going West past some stacked rocks before the path veers South and stops suddenly at an outcropping of rocks - and here you’ll find a special Zelda-themed chest. Once you reach the Throat of the World, you’ll find a level plateau just below the peak where a dragon tablet (and perhaps the main dragon himself) are located. There’s no easy way to do this - you just need a lot of time and patience.
However, intrepid mountain climbers can always try and another way by hopping, sliding, and hugging the cliff walls to make it all the way from High Hrothgar and bypass the barriers to get to the Throat of the World.
