heloo people, i am not a real black smith or anything but i am an enthusiastic new metal worker and i make improvised swords and stuff
i live in quite an urbanised area but there arent really any advanced hardware stores around, so i usually have to make a barbecue fire or use the kitchen stove and collect junk :D and i dont have access to proper steels. recently i started work on a knife, it normal iron,the type used by welders for making gates and ladders ( its not steel as far as i know) , and i need to harden it as much as i can because right now its not much use as the edge isnt durable, what exactly should i do? i have no access to torches or a forge or power tools, basically im in the medieval times :D what should i use to quench this knife? used motor oil or water ? pleeease help me out i really need help
