Polishing (an idea for the potential combat update)

Tools and weapons are able to be polished with a diamond and relevant polishing materials inside a grindstone. Chain sheet is crafted with two iron chains to make one sheet, and would be used for polishing and to finally make chain armour in a normal material configuration. Sandpaper is made with either sand or gravel, a slime all, and a piece of paper. To polish any "hard" tools (iron, gold, stone, diamond, copper, and netherite, sword and tool sets, mace, and trident,) You would put them in a grindstone with a diamond and a chain sheet, this would polish the item and give it +0.5 damage and +10% mining speed but -15% durability, polishing can happen up to four or maybe five times and consumes the diamond and chain sheet. Polish any other tools made of wood (wood tool set, fishing rods, etc) would be the same but with a diamond and a sandpaper and add +0.5 damage, +10% mining speed, +10% mount speed, +10% casting range, +10% leeway on the window of catching a fish (like when the bubbles pull your bobber down you have more time to pull it) and -10% durability. This could add a new way to improve lategame tools effectiveness at the cost of durability. For example a maxed out polished sword would have an extra 2.5 attack damage but would have only 25% of its max original durability. Balancing cost versus reward.
