How to break up and mix SN?

[NitrogenAfternoon]

I am reading so many conflicting posts that I need some straight forward and direct answers.

what is the best way to break up SN? It is hard and brick like, just the way it is supposed to be. I've read posts that we shouldn't make direct contact with it using our hands. I've also read posts that it shouldn't touch metal due to corrosion. So what exactly am I supposed to do when I open it from the vacuum sealed package? How do I handle it? And how do I break it up?

Once that is done, what should I use to mix the SN? There is a lot of conflicting answers on this too. There is saying no metal spoons, then it's okay to use metal spoon. Then people say no plastic, and some say it's okay. So what is the deal here? A Glass cup and a plastic spoon? Or is glass cup and metal spoon okay?

Please. I need every detail to go well, as I plan to ctb in just a few days.

I'm assuming it's a DMC source, so is it still in the sealed pouch? Mine is, and it also feels like a solid brick. I've heard that once the seal is broken it turns to powder, though.

I personally haven't seen anyone advise against plastic, so that will be my option. In Goodbye Threads where people have uploaded photos, the majority can be seen to have used plastic cups and mixing tools.
