I've avoided this thread (beyond reading it), but thought I would make one post in defense of the "steel snobs".
The standard reply from those who defend mystery steel is ,"I did it and it worked for me.", or " I've done it for years, and it worked for me."
That may be true, but ,will it work for others? Will they have the same steel source...or the same equipment.....or the same experience to meld these two into a good blade? While using a known steel won't guarantee a good blade, it certainly may eliminate one of the biggest variables.
I would agree that most smiths could make their 1001st blade out of a tried and tested mystery steel and get good results. I think the other side would have to agree that a new smith, who has never make a knife, would not be able to tell good steel from bad, nor have the experience to know what the steel was telling him while working it.
The better second source steel arguments have been pressed by those who pointed out that the steel they used was recycled but they had properly researched the make-up and content. If you know (really know ,not suspect) what the steel is, then it is not a mystery steel.
A common statement is that ,"Blacksmiths/my Grandpa/John Q. Smith/etc. didn't have anything but recycled plow /saw/bearing/etc steel, and he made 10,000 knives. OK, how is that pertinent to the discussion that modern known steels are a better way to start? These forefathers had no reliable suppliers, no internet to get advice, and had to develop their own techniques (and usually build their own equipment). They also made $1.25 an hour ,or less. Is that the advice we want to give new smiths?
Now ,in defense of the steel snobs:
Most posts that end up in a steel war are posted by newbie smiths who ask a question about what would be a good steel to start with.
Or the post is something like, "Is a lawn mower blade a good steel..." ; " Can I make a knife out of rebar....."; or,"I found this piece of steel out in the alley (It looks sort of like a bed frame)...."
For good reason, we don't usually suggest that a smith start out on a 100# power hammer and make a damascus billet. We try to give the most even path to getting started with the fewest pitfalls - Basic equipment.....Basic (but complete) knowledge of the process.....and basic reliable steel. The rest will come with time and skill.
I will always advise anyone who asks me, to use the three pillars:
1) Use a Known steel
2) Learn and understand the heat treatment process
3) Start simple and work up to complicated
The shortest path to these three pillars is:
1) Start with a basic eutectoid steel, like 1080/1084, from a reliable source. Stick with that steel until you understand it well.
2) Before purchasing/finding the steel -gain basic knife making knowledge by reading books and studying the HT, knife making process, and basic metallurgy online and in places like this forum .Your Gramp ( and me) never had these advantages.
3) Practice, practice, practice. A drop point hunter is a good knife to start on.
