(+/- X micrometers)** A: This goes to 0.5 MM, which is 5 micrometers. **Q: Can this replace a metal blade in a combination square? i'm a novice diy woodworker** A: No. The combination squares I'm familiar with typically have a channel that runs the length of the rule which is provided to allow it to be locked into place when adjusted as desired. This rule does not have that channel. **Q: Curious, whats this country of origin of this rule?** A: Japan. Very nice rules. **Q: Is this really sand blasted finish? I am looking for a ruler wirh zero glare to be able to see it easily** A: Here is the Shinwa scale on top of another brand I bought at the same time. The Shinwa definitely has a non glare finish. I did move them around so you can compare for yourself. Additionally, the Shinwa model has stayed flat and the edges while being sharp are smoother to the touch - the other rulers edge seems almost sharp enough to cut if you ran it across your hand. I don’t think you will be dissapppointed in the Shinwa, ## Frequently Bought Together - Shinwa 12" 300 mm English Metric Rigid (1.250 wide x .040 thick) Zero Glare Satin Chrome Stainless Steel E/M Machinist Engineer Ruler/Rule with Graduations in 1/64, 1/32, mm and .5mm Model H-3412C - Shinwa H-3412A 6" 150 mm Rigid English Metric Zero Glare Satin Chrome Stainless Steel E/M Machinist Engineer Ruler/Rule with Graduations in 1/64, 1/32, mm and .5 mm - Shinwa 150 mm Rigid (15 mm x 0.5 mm) Zero Glare Satin Chrome Stainless Steel Machinist Engineer Ruler/Rule with Graduations in mm and .5mm Model 13005 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/6458209-12-300-mm-english-metric-rigid-1-250-wide-x](https://www.desertcart.us/products/6458209-12-300-mm-english-metric-rigid-1-250-wide-x) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-13*
