Smithing Table Recipes

So as of right now, it just gives you the ability to turn your diamond tools/armor into netherite ones. I propose to give it the ability to add more to tools in general. One idea that came to mind was adding leather and any type of tool, giving it a grip. This gives the items some nice bonuses.

Sword - Makes your crit bar recharge faster, so you can potentially land more crits.

Pickaxe / Axe / Shovel - Makes your tools break blocks faster. (equivalent to a lvl 1 eff)

Hoe - idk

As I was writing this, another idea popped up and that was to add another branch. What I mean by that is what if you had the option to turn your tools excluding the sword, into weapons?

Say if you put 3 iron ingots and an iron axe in a smithing table, it would craft it into a battle axe. It would kind of make it too OP though as the axe already deals a heck ton of damage, so I think the normal axe should just not do as much, so that once it turns in to a battle axe, the changes will seem more dramatic/impactful.
