Suturing
Knots you can join a kink bondage group (ha ha)that does rope work. Or go to sailboat place and look for crew positions believe me you will learn knots and nav by star and compass if you go to the places without all the fancy stuff
You want to see what its really like go to pig/cow farmer and ask to help de nutting pigs don’t even get stitch the testicle once pulled till they snap create a vascular contraction so little blood and a lot of squeal. Nothing prepared you for a massive blood injury. You will never forget it and frankly without serious skills with 1000 of hours and special tools all you can do is stitch surface cuts because you won’t have right stuff to debride ànd clean and check a gun shot nor tie of and re sew vascular system. If you are doing at home things are seriously messed up and hygiene will not be there death from infection will be end of most injured along with tetanus as there wI’ll be zero way to treat by I saw it on you tube crowd.
Saw sharpening most big saw require a guide without them you are up the creek. Axe and falling same as chain saw.. if you don’t know go and get your faller certificate it’s in alot of night schools. Can’t learn well by video need to have a feel for tree ,weather, slope of ground surrounding trees. The trees make sound when you get past a certain point chopping. Wedges are nessisary. Axe sharpen is like a knife learn to use a file at set angle it varies from type of axe but you should be able to shave with it.
Metal tools take a life time to master no amount of watching will do anything need to go and get hands on. If you want to learn go find a place that will apprentice you in stuff you want to make. Many different types of metal work no one does it all. No short cuts
After reading your replies I take it you are a younger gentleman. There are no shortcuts on skills they come at the cost of thousands of hours of hard work and atleast a pound of dumb meat which you will cut crush slice and burn off you along your way to enlightenment.
Most skills are perishable which means you need to practice regularly so pick something and get good at it that list is too much for one person in a life time to be any good at all of it.
