Дамы и господа, объясните мне как подтягиваться на крюке? И есть ли у других инструментов какие-либо назначения, кроме как "бить"? 

Ladies and gentlemen, explain to me how to pull up on a hook? And do other tools have any purpose other than just "beat"? 

use the scroll wheel of your mouse to change length of cords. If you're using the hook for climbing, I would recommend getting a second one and putting it on the crafting table to get two half hooks; they do not link stuff together so you won't accidently lose them climbing higher than you can reach
