Do I need a magnetic square?

Most choices of tooling in grinding, like any other machine, boil down to convenience for "quick" work. Quick being relative when it comes to grinding.

Yes to true, proven, tooling vises. Including sine vise.

yes to all the magnetic transfer blocks you can accumulate. Prove/make a few dead square and reserve them for that use. I have one cube i scraped, and use it only for grinding other grinding fixtures and blocks. Magnetic transfer blocks can also be machined or ground with steps, angles, step-angles, slots, containment bores for small flat parts, tapped holes, etc, etc, etc. for multi-part job runs.

Transfer blocks are routine for using to block other fixturing and tooling set ups, including small vises, spin fixtures, etc. Though simple parallels and steel blocks can be used as well/instead.

Yes to at least one single angle sine table. Preferably magnetic sine table. I rarely use the compound magnetic sine table, but it can come in handy. Even when used, it is often used in one tilt axis only, but the extra size is sometimes an asset.

Some small parts are angled using a projecting fixture on a 5c spindex, or in the Vee-block on a master-grind type.
If the clamp will not interfere with the feature to be ground, Vee-block can be held tilted sideways in tooling vise jaws referenced at set up with a protractor. Etc.
