Vern,
Welcome to the blades forums.
A search on this topic will reveal a lot of discussion about what steels are "BEST" for which purposes.
The general answer is that most all steels with over 60 points of carbon will make a good knife.The primary things you need to determine are:
What equipment/procedures will I use to make this knife ?
Can I get this steel in a continued supply and quality?
Do I know the properties and heat treatment of this steel ?
With those questions in mind pick a steel that you can get a continued supply of from a known source. If you are using John Deere hay forks, and you will always have a good supply, that is fine. Just contact John Deere and get the specs on the steel. (Most long time makers will tell you that the steel source should be well known, and ordering steel from a supplier is far better, as the quality and content are assured.)Then learn all you can about the forging and heat treatment of that steel type. Use the right oil for the steel type, and temper at the proper temperature and times. Master this steel and make lots of knives from it before jumping from new steel to new steel. With a good steel to use, a continued supply, and mastery of the steel, you may never change the steel you make your knives from.
Short answer would have been , "There is no 'BEST' steel." (But I rarely give short answers)
