Roy Underhill - take a moment and look him up.
When I was starting to build things, it was out of wood. I started stocking a small wood shop in an unfinished basement. There were two shows that taught me more than I can say. Roy Underhill all by hand, the old way and Norm Abrams precision, the new way. I use both but this post is about hand tools.
My shop teacher in Junior High was about learning basic skills. A hand plane, a try square, and a piece of 2x4. Make it true and square. That was a lesson in what can be done by hand.
I make English Longbows and they are precision objects the need fine adjustment. That adjustment is done with scrapers. I purchased many, but I wanted my own. Woodsmith has really great plans so you can make your own. And so I began. I had some sugar maple and some walnut to I roughed out the blanks to dimension and made the inserts.
Next comes cutting the throats for the scraper blades. This was a but of work setting up but take a little care and the come out fine. You can see that they are on an angle to allow shavings to come out.
Using the plans you paste on a guide to bandsaw out all of the blanks to make a profile that fits in the hand. Cutting to a guide requires working out the order of the cuts and saving the cut off pieces to move to the next cut. Take time to work out the order of operations.
After the bandsaw and sanding you something something like this. A visit to the drill press and a countersink and you have the holes for the great brass hardware from McMaster-Carr. I get hardware from them for special projects when you need the brass.
Now I have the holder, but I need the working edge. You can order all sorts of card scrapers, but I had a few on hand that I was ready to cut into pieces. You can scribe them with a file and snap them or cut them with a hacksaw. There are four different scrapers. One to chamfer an edge, a small half round, a large half round, and a flat. If you look below, you can see how the profiles have been sanded in the body of the tool. Then the pieces of scraper also need to be modified with a drum sander or files to match.
Now some sort of a finish (I used a wax) and you have you personal set of scrapers. After use they will get all that patina of well used tools and they will last for as long as your work does.
Of course this whole exercise would not be complete unless they actually do the work intended.
