One of the key advantages to track saws is built right into the track – the sacrificial strip that becomes the cursor used to ensure you cut exactly where you want. This jig simplifies the process of setting up a new saw (or a different-width blade) for use with your existing track, without having to replace the sacrificial strip. For those who use more than one saw, this avoids the trouble of having a separate track for each; it also spares the extra expense of purchasing a new sacrificial strip if you decide to upgrade your saw.
