Recommendations for cooking techniques

Hey all - new to this channel and I'm looking for recommended Youtube Channels or classes that teach you technique (things like best approaches for chopping, how to hold your knives properly, etc..) Basic fundamental 'how to do things the proper way' and less 'here is how to make ravioli'.

If there is another thread this information can be found in, a link there is great as well! Don't want anyone to feel they need to rewrite something you've already written elsewhere.
