### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    VERY NICE; WELL MADE
  

*by M***E on Reviewed in the United States on June 10, 2021*

My work output is strictly in metric. I bought a LaSquare several years ago even though it has only an imperial rule (shame on LaGesse Products). This PEC 300 mm Zero Glare Metric (.5mm & mm) Replacement Machinist Combination Square Blade fixed my broken LaSquare. See the photo

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Doesn't meet 1" Width Specification. Is Actually 0.995" to 0.997" Depending On Where Measured
  

*by B***B on Reviewed in the United States on March 30, 2016*

In my opinion:Ok, but one star off as it doesn't meet it's advertised width spec of 1". I'd planned to use it in part as a spacing gauge for an operation we frequently perform, but no dice.It's actual width is 0.995" to 0.997" depending on where measured.Review posted 3/30/2016, and will be updated should experience warrant.***
