This addon changes all the tools in minecraft to be hd and simple. Being that this is an addon it can be used seamlessly with any other resourcepack just by putting it above any other resource pack you have applied. The reason it works so seamlessly is because these tools are the only textures in the entire pack there are no other textures in the folder.
