Bert, The best, for pattern, I have used is elevator cable . I also really like sling/choker cables I have been told they will have a tag on them telling you what they are. Improved plow steel, extra improved plow steel or extra extra improved plow steel, google for information, all three make good blades. Mystery cable is going to be a hit or miss on heat treat. Don't use galvanized unless you are ready to meet your maker, toxic fumes. If someone reads this that knows more than I do, on the subject of cables, please feel free to either correct me or add helpful information. I am by no means an expert on the subject and wouldn't want to put out incorrect info.
If you have a local bladesmith in your area I am sure they would be willing to help with the process.
Hope this helps.
