Oscillating Multi-Tool
  |
You've probably seen this tool before even if you don't recognize it's name. Besides being called an Oscillating Tool it's also referred to as a multi-tool, a Fein tool, or a Vibratory Saw. Although it has many attachments for sanding and shaving, it's primary use is as a saw.

Saw Movement
With a Vibratory Saw the mechanism swings your attachment left to right a very small amount. It pivots so little it seems more like it is vibrating than actually sawing. This is what allows it have so many attachments. This movement does make it hard to cut a straight line however. So if you want a nice straight line just follow a straight edge, keeping the blade flush with your guide.
Attachments
There are a lot of different attachments. There are two kinds of cutting blades, straight and round. I find the straight blades to be more versatile than the bulkier round blades. But each have their use. The round blade is better for long straight cuts. Straight blades will be better for plunging or making small detail cuts. No matter what blade you use, always score your cut line before digging in deep. Also, don't put too much pressure behind the blade. This will lead to too much heat, dulling your blade and increasing the chance of breaking the blade.

Always use the proper blade for the material you are working with. You'll notice there is a large variety of blade types, since this tool has a lot of uses. The three blade types I usually have are bi-metal, wood, and carbide. Carbide is where it's at. Buy these. They are more expensive, but they last longer than any other blade and can cut most materials. Another popular blade is the diamond tipped. You only use these blades for grout removal and a round blade is usually preferred.
