In looking at some of the other build threads I thought that I'd share some of the tools that really help me building. For instance, here is one (actually two) of my favourite tools

I use these very miniature planes when I'm shaping wood, like leading edges, or shaping trailing edge stock to become ailerons. There are all kinds of useful little tools that you or a buddy uses that makes all the difference.

What are they and how do they help? Are the available online?
