Golden Axe
To receive the golden ax, it would appear that you need to break 100 axes. You will be able to only get to 100 in case you keep using flimsy axes on your tree chopping needs.
Golden Fishing Rod
In New Leaf, you can unlock the golden bamboo fly fishing rods by catching every fish for sale in the game. It seems like this can be the same result for catching every Animal Crossing: New Horizons fish, and accomplishing this will get you the golden fly rod again. It's going to take a little while to find the answer though, as fish appear seasonally and show off at specific months and points during the day.
Golden Net
Like while using the golden fly fishing line, previous games gifted you a golden net for catching every bug accessible in-game. The same is true for catching almost everyone in the Animal Crossing: New Horizon bugs it appears, so strap looking for the long haul for this.
Golden Shovel
To obtain the golden shovel, you will have to help Gulliver 30 times there's an Animal Crossing: New Horizons Nook Miles Rewards linked with a similar amount too. It's going to take you a minimum of 30 weeks of play in achieving this though, therefore it is going to be a little while before we've waving golden shovels around-not comprising those cheeky time travelers though.
Golden Slingshot
You can purchase the golden slingshot by popping 300 floating balloons that have a normal slingshot.
Once you've popped 300, watch the skies for the present stuck just using a golden balloon. It's on this gift that you will receive the golden slingshot recipe.
Golden Watering Can
You can unlock the golden watering can by achieving a five-star island rating. After you've achieved this, Isabelle herself will ping the golden watering can recipe for your phone.
How to obtain gold nuggets
For many of these golden tools though, you will have to grab yourself a golden nugget. You can get these like as you find Animal Crossing: New Horizons iron nuggets, by smacking rocks with the ax or shovel. They're quite rare, however, you can usually select one a day, or every second day, depending on how many Nook Miles Tickets you're utilizing daily. You never have to worry that ACNH Bells is not enough.
You can get all the ACNH Items you want for only a few dollars. If you want to experience the unlocking process more, Buy Animal Crossing Bells can also help you when you need it.
