SPEARS ARE TOO EASY TO CRAFT

I suggest to make the spears hard to obtain since it is so overpowered even more than the mace and the worst part is that players can obtain it during the start as soon as the world is created and its not good for a game that is meant for surviving. My idea is to balance the spear's overpowerness with making it hard to craft i suggest  using the heavy core in the crafting recipie since its hard to obtain and it makes sense sinse the 2 most overpowered weapons are made from the heavy core. First the player have to use the heavy core and diamonds to form the hard diamond core and then use the fletching table to trim the hard diamond core into a diamond spearhead and then use reinforced sticks to craft the spear. then it can be upgraded to netherite using the smitthing table.
