The TrueCut Ruler (3" × 8") from The Grace Company features a "Ruler Track" that perfectly interlocks with TrueCut rotary cutter guides, delivering stable, straight, and slip-resistant cuts with each stroke; its grid markings in 1/8‑inch increments include conveniently labeled ¼", ½", and ¾" measurements, while angle guidelines at 30°, 45°, and 60° enable versatile cutting. Additionally, the ruler incorporates built-in marking slots for fabric labeling through the ruler, dual‑direction numbering (left‑to‑right and right‑to‑left) for effortless orientation, and is crafted from durable, chip‑resistant injection‑molded thermoplastic for added longevity and flexibility.
