I think changing the command block weapons' textures into the storymode ones are cooler. (except the command block sword, it's already the storymode one)
The command block axe and command block pickaxe in the storymode are so cool !
Pictures of them:

The textures aren't gonna be changed, I've talked to Cracker about this before

Oh, sry. I've missed that

Textures aren't changing as they're meant to emulate vanilla minecraft

This mod ISNT Supposed to be a 1:1 recreation.

If you want new weapon textures, here is the link to the Texture Pack
