After getting the chisel sharp, I would take the beginner through a series of lessons demonstrating various uses of chisels, but I'll skip those here as readers of this blog are familiar with what they would contain.
What's next? So far, I've spent about $90 of the beginner's money and next comes the biggest expenditure I would recommend. A plane is the next tool logically; after all they're just chisels in guides. My opinion is that, if you can afford it, you should own one new premium plane and it should be your first (I'm ignoring wooden planes for the simple reason that I know little about them.). It's what I did by accident and I consider myself lucky. The new plane works right out of the box, important since the beginner doesn't know how a plane should work. A second reason is that I think you need to own one low angle, bevel up plane, one with square sides that is suitable for shooting. Equipped with three or more blades, it has unmatched versatility and simplicity. You'll never outgrow it.
This is a big expenditure, about $300, a major hurdle for a beginner. You can definitely do without it. The other alternative is to have the beginner get an old #5 and refurbish it, which might well be preferable. I'd have them follow Bob Rozaieski's video.
This is a major departure from my friend Bob's recommendations in his podcast series and I definitely respect his opinion. The smoother and extra blades I bought cost more than the seven old planes combined that I own. I have never wanted another new premium bench plane, but I am really glad it was my first plane and I am glad that I have it. If, as their skills increase, they decide they don't want it, it could easily be sold at a good price.
The bad news is, they've spent almost $400; the good news, it gets a lot cheaper the rest of the way. As I look at my tool chest, I can honestly say that there isn't another new premium tool in it that I really need. I have a number and I really like them, but I don't need them. There are good vintage alternatives for all of them. As I've gone along, I have enjoyed finding and refurbishing vintage tools more and more.
