General gear update PE

Imagine the addition of spears and daggers to Minecraft. A dagger, although weaker than a sword, would only need one of the unit in question. Also, a spear could be crafted from 2 sticks and a dagger. Also, I imagine lots of players would love a light that could shine without being placed and held in their offhand. In my opinion, PE users such as myself could benefit from being able to hold a sword or an axe in their offhand slot. Plus, the addition of several gear types might be pretty cool for those of us who cannot use mods. These new types could include (but aren't limited to):

emerald (similar to diamond but with a better attack speed).

redstone (which could set TNT alight with a strike and would be of similar value to iron)

lapis lazuli (which would mean you needed no lapis to enchant it)

copper (because, in my opinion, it does not have many huge uses on Survival)

amethyst (for the same reasons as copper)

obsidian (because a level above netherite would be awesome! Imagine how powerful it would be!)
