As a newbie in this field, one of the first and most basic things you need to learn are the different types of tools and their intended use. A glossary, if you will of the myriad names for each of these implements. Getting into this I've noticed that in carpentry, there are often many names for the same tool. I'm not sure why this phenomena occurs, I can't imagine a blender being called say, a "spin chopper", or a fork being called a "mouth rake". But take the power saw for instance. There's a rip saw, circular saw, table saw, sawsall, reciprocating saw, scroll saw, jig saw, band saw, rotary saw, radial arm saw, mitre saw, miter saw, compound mitre saw, chop saw, sabre saw, saber saw, cabinet saw, and I'm out of breath. The problem is, these 17 names represent 2 saws!! Ok, that's an exaggeration, but they represent 6 or 7 saws. For every saw there are 2 to 3 names. Who did this and why is my question. It's hard enough when you have no idea what the freakin thing does, much less trying to manage the different names. What happens on construction sites? Do they vote on what name to use? Do they alternate so as not to offend the other less used names? Does sabre saw feel deficient because of the big jig revolution of the 70's, rendering poor sabre nearly obsolete? So many questions. My head hurts, so I'm gonna go cut something with my jigmiteriparyarm saw.
