The next hand tool every woodworker should have is a nail set. In fact, you should have several sizes. They look like awls, and you use them to drive nail heads into the wood so they are flush or right below the surface. This allows you to fill the holes and prepare for staining or painting. The nail setter will usually have either a convex or concave surface to grip the nail better and keep it from sliding off and marring the wood.

Adjustable shelves beat fixed shelves in just about every way. They make storage and display space more versatile, of course. And they’re usually just slabs of plywood nosed with strips of wood or edge banding, so they’re easy to make. And because you can remove them, adjustable shelves simplify staining and finishing. The easiest way to support adjustable shelves is by using shelf standards are ($3 for 6 ft. at home centers). Just screw them into place and you’re done.

Start by building a base out of 1x or 2x lumber. Make its depth 1 1/2 to 2 in. less than the depth of the bookcase itself. Its height must be 1/8 in. taller than the baseboard molding you plan to install to make sure the molding slips in easily. Set the base into position and check for level right to left and front to back. Fasten it to the wall studs using 3-in. drywall screws [ 1 ]. Also drive angled screws through the inside of the base and into the floor.
Bruce Lamo has done woodworking pretty much all his life, although never exclusively to make a living. He prefers making furniture and working with solid wood, but often uses plywood when making cabinets. This article originated when a few friends were considering buying tools that based on his experience, he thought would not be a good investment. 

So my partners and I opened a Woodcraft store that had an established school as a main part of its business plan. What could be better? Come for a class and buy some tools. But when I first presented the idea of a full-fledged school to the corporate people and told them the dollar amount that I planned to do in school tuition sales, they basically laughed at me. A year after we were opened, they finally started to take notice of this whole "education thing" because I had not only met my projections, I doubled them.
The next important hand tool for the woodworker is an accurate tape measure. Get a retractable one that is at least 25 feet long. Any longer than that, and you start having problems getting it to roll back up. Since measurements on large scale projects can be very susceptible to even the most minute measurement variations, you’ll want to make sure the “hook” or tab at the end of the is firmly attached, with no give. When they get loose, you’ll have as much as 1/8” variation in your measurements. This can add up to some severe accuracy problems in the long run.
