Sure it's nice to use super high end steels. But it sure stings to waste it when you screw up a blade, which happens a good amount in the beginning.
As far as making 10 versions of the same blade, I don't think Stacey was nessecarily talking about doing them all at once. If you make the first one and have an issue with the profile or design, you can change it on the next one. A lot of beginners try to do too much in the beginning. IMO, an awesome knife is one that is well made, down the the smallest details. If you look at the master bladesmiths, they make knives that have an EXTREME amount of detail. They're able to do that by focusing, to a high degree, on that one blade. The level of which a person is able to focus in on making something is going to determine the quality of the results. By resisting the urge to bring a bunch of different ideas to fruition at once, you'll be able to focus more, learn faster, and in turn make better knives.
I get it, when I started making knives I had a bunch of different ideas about what knives I wanted to make. I made a handful of different blades at once. It took a lot of time to get them all done and they weren't nearly as nice as they could have been. That was because each one didn't have my undivided attention. My mind would wander around the entire batch of knives instead of just the one. It was distracting, inefficient, and I probably moved slower along the learning curve.
Once you make a good amount of blades you'll have refined your designs to a point where you're happy with them and in turn crank out a bunch at once, assembly line style. If that's what you want to do. Of course, if you're trying to constantly evolve the level of embellishments you're able to do, it's still probably a good idea to do one at a time. That's how a lot of higher end makers do it.
Good luck and nice start!
