Buddy of mine works at a truck accessories shop that also re-vamps trailers. Scrap hopper usually has a set of new or barely used leafs. They thank me for taking them to free up space in the hopper
If I started making blades now with what I dragged home, two things would occur. 1: I would die in many years, single and still penniless, and 2: I will still have lots of springs left over. Then there is the possibility of ripping a hole in the fabric of the universe if I actually complete another knife in this lifetime ..... Basically speaking, springs are not hard to obtain if you just do a little research
