Getting Attack Damage Value From Held Item

Hello! I'm wanting to make a mod feature that restricts use of weapons with higher attack damage until they reach a certain level in a skill, but I can't seem to find a way to get the value that's listed in the item's tooltip.

I DO NOT want to use the method of grabbing the attack value after hitting a mob as there's many variables at play here like a wooden sword used with a strength potion making it damage similar to an iron sword, and the procedure disabling it due to thinking its a better weapon. I am only looking to grab the raw damage number from the weapon itself.

if possible, I would also like to do the same for attack speed, armor, and armor toughness values. Thank you all in advance!
