Yep, at 11 I thought I knew it all. I could do that...no problem! I was pretty proud of that knife until I made a few more, then it started looking more and more "wrong".
Today, I pull it out to show someone I am teaching who thinks their first knife looks bad. The first knives today, with all the help available from the internet and places like Bladeforums, are miles ahead of what kids could do alone back in the 1950-60's. Back then, even Bill Moran was trying to figure things out by trial and error.
A look at the past:
Many of the members here have no idea what the world was like before the information revolution.
In the 1950's there were no books on knifemaking. Most info was just a short reference in a blacksmithing book.
There were no knifemaking clubs, no societies, no groups. There were less than 50 custom knifemakers in the USA. Hobbyist knifemakers numbered less than 1000.
A few books on metalwork may have been found in a public library. Most of those were written in the 1800's to early 1900's. Many make no reference to electricity.
If you were lucky, a nearby blacksmith would show you how to shape and harden a blade.
If you were really lucky, a maker like Bill Moran would show you a few things. Even those makers may have been doing things the hard way ( or the wrong way) because they had no one and no books to show them any different.
The choice of knife steel was limited to found items and a few basic industrial steels. Terms like German Steel and Silver Steel meant quality ( even though no one knew what was in those steels). Instead of discussing the attributes of carpenter 5160 vs Admiral 5160, they argued Ford vs Chevy springs.
The few makers there were closely guarded their secrets. Many had very wrong HT processes. Almost no makers had any understanding of metallurgy or what happened to steel during knifemaking.
HT was close to magic only 60 years ago. We joke online about doing it at midnight and pointing the blade north....but that wasn't a joke at one time.
Today you can google any topic, reference, data sheet, etc.
There are tens of thousands of experienced makers and millions of hobby makers worldwide...and they can all talk to each other on the web.
Info can be found in seconds, not days or weeks...if at all... as it was 60 years ago.
