I am not going to re-cap all the previous post, but will tell folks a bit about Aldo.
Most people get into supplying a niche market by being a used who decides to become a supplier. I would say that 99% of knifemakers started making knives to sell by starting to make knives for themselves. Handle wood suppliers often get started as suppliers by selling off their excess to support their own buying. Most full business suppliers realized that the only way to make money was to offer all sorts of things. Most knife suppliers sell everything from steel to epoxy. Some have been doing that quite well for a long time.
Steel suppliers mainly consider a single bar of steel order a waste of time. They sell in tons to industry. Some tolerate knifemakers, and others just aren't interested in us. The make-up, alloying, condition, etc. of the steel they sell to industry is for their needs...certainly not what knifemakers want. If people who want 100,000 pounds of a certain steel don't really care what the actual make-up is...then knifemakers don't have ant say in the discussion at all. Additionally, steel is generally made by melting scrap steel and adding some new iron and then adjusting the alloy to the requirements of the melt. All the extra stuff in the scrap gets in the mix. Industry doesn't care, as they are mainly concerned with yield strength and such. The amount of the lesser alloy ingredients are of no consequence.
Aldo wasn't a knifemaker, and got started because he met some great knifemakers at a hammer-in with Bill Moran. He listened to all the talk about steel and how hard it was to get this and that steel anymore. A light went on! Being the opportunity seeking Italian he is, he thought..."Hey, I could make a fortune at this.". Years later he was thinking, "Hey, I could loos a fortune doing this!" But, he stuck with it.
He had epic problems, health and family issues, financial problems.... including having his entire steel stock stolen at one point. He lost his good looks ( OK, he never looked all that good). Not getting out to the Lincoln Center and the Met, he lost all his class......OK, he probably was never any classier than he is now

. He ate peanut butter and drank tap water... But most important, he kept listening to the makers about what was needed and what was hype. What he heard most was that no one really knew what they were getting. L-6 form two suppliers wasn't the same...some wasn't even L-6. W2 could vary a lot, same for many other steels. Basic low alloy forging steel was really hard to find. The answer was obvious...get each batch tested and know what you are selling...and don't buy what isn't right.
The real
New Jersey Steel Baron title was earned when he had his first melt of 1084 make. Back then it was a mere 15,000 pounds for a run ( today it is ten times that). It was the joy that new makers and forgers were looking for. Subsequent batches used the feedback from users and he added a bit of V and some alloy tweaks to get 1084FG. This was great. later on he added the popular stainless steels, and introduced many to CPM-S35VN...a really great cutlery steel.
He got tired of hearing complaints about sheared steel, and spend serious money to buy his own saw. He heard that some folks hated mill scale..so he got a surface grinder.He has the steel spheroidized...because knifemakers really like that. His son venture into water jet cutting.
He would have a glass/bottle of adult beverage and enjoy a cigar with makers at Ashokan, Atlanta, and other places...and listen to how US knifemaker who made high end professional cutlery hated that Hitachi wouldn't sell us steel. He talked to many of us about alloys and reasoning and finally made a deal through Germany to send a boatload of Hitachi steel our way. Other steels are coming.
Why does he do this???? - Because he loves us dirty hands folks.
Could he make more money selling plumbing supplies ??? - Probably much more!
Does he deal with only knifemakers and sell us what we need and want... - Absolutely!!!!
What does he do best???....- LISTEN to his customers.
That is why he is one of the first name off our lips when suggesting a supplier.
This is not to say that the folks at USA Knifemakers, Jantz, etc. are not good suppliers...just that Aldo only sells steel..and that is why he os the New Jersey Steel Baron.
