Weapon Additions

I would personally love a more diverse set of weapons to use. Seeing the Spear being added to the game makes me excited to be able to use a new weapon as my main source of defense! With that being said, I think the weapons should be more diverse. I've never added feedback before because I always come  to love the updates, even if I'm hesitant at first, but the spear has reignited my interest in this game and has gotten me back on to try and do the things I haven't, like completing all the achievements before new ones come out just so I can say I have finally completed every challenge in Minecraft. For starters, maybe new ranged weapons outside of the crossbow, bow, and Trident. What if you could have a weapon that never leaves your side? Something that will return to you without enchantments, with the drawbacks of it being somewhat expensive? Like a Knife and Chain? Having the ability to have ranged and area attacks that give the player a slight sense of safety when covered in mobs? The knife could be a separate tool or weapon, but when attached with two chains, becomes a very light hitting but very important add to any combat enthusiasts' arsenal. More as a Utility item than a stand alone weapon, this could give players a chance to open a pocket to run away during a difficult fight. And enchants could work similar to Knockback and Sharpness, giving the knife more recoil against enemies without being able to do a lot of damage. Or even making it capable of Grappling?
