Infinity Tools 46" 精密ストレートエッジ用定規

Used this to set up a pair of router tracks and the machined 1/4" channel kept both rules perfectly flush, no fiddling with tape. The 46" length felt rock solid across my whole workbench, and it's stayed true after a week of heavy use. Exactly what I needed for repeatable dados.

The channel is dead straight and deep enough that my rules sit flush without any wobble. I swapped in a metric tape on one side and a fractional rule on the other, so I’m covered for any job. Took me an afternoon to set up, but it’s been spot-on every time since.

The machined 1/4-inch channel on both faces is a clever touch—I slid two different rulers in and they sit perfectly flush against the reference edge. This thing feels solid and true; definitely my go-to for long cuts now.
