    Sharp little blades!
  

*by M***L on Reviewed in the United States on January 8, 2024*

I took a chance on the four inch version and replaced my double square blade.And I loved it so much I bought 3 more and 4 of the six inch blades for spares.They read easy. Are bang on and they lock up real nice.Im going to give them 3 thousandths of error on the eighth and one and a half on the sixty fourth.The four and six inch blades both get 3 thousandths of error to my heighth checker. Which has one. And the table, which has one but it's just a little worn in, so I'll give it two.All added? There's your three.Bang on square blades as I said.They are for small squares.I could see some cheaper six inch multi squares having a tough time gripping it.If your screw bottoms out before it's tight?Shave a bit off of the back of the head of the screw and it will come down for ya.Mine fit fine but I prefer a double square and they're a little smaller by design.I would happily buy these again and actually I did already. And I have spares.Heck I about got a dozen of em.

    Precision marking
  

*by D***S on Reviewed in the United States on December 27, 2022*

Love this guy. I also bought the 6” metal ruler too which fits. I can use either ruler interchangeably which is awesome. Accuracy is perfect when measured against my machinist squares both for measuring and squareness at 4 and 6”.
