### ⭐⭐⭐⭐⭐ 







  
  
    Remarkable perfection for a ridculously low price
  

*by S***N on Reviewed in the United States on 19 September 2018*

I read about Jo-blocks in Simon Winchester's recent book, "The Perfectionists."  He writes about them in the prologue.  I just had to have them.  I think mostly I purchased them because 15-20 years ago a set not as good as these would cost north of a few thousand dollars and maybe more.  Today - they cost less than $100, all because of the things outlined in Winchester's book.However, the embarrassing thing is, other than ensuring my digital calipers are spot on, I can think of no other uses for these as yet.  I'm not a machinist and don't have tools (other than my digital calipers), that need anywhere near this level of calibration.  But they are just so wonderful and perfect, I can't help taking them out and just looking at them.  If you know of any other good uses for them, I'd love to hear about it.

    My blocks went through calibration but they had grime on them and no oil paper wrappings
  

*by B***L on Reviewed in the United States on 13 November 2023*

All of that can be overlooked since I can clean them and oil them properly, but the one thing that I wish I had realized before purchasing these was the fact not all of them were the same dimension when stacking/wringing.  If you are trying to measure an accurate cutout hole or slot on something, if you are using a thinner block in your stack it will get pushed.  If all the blocks had the same dimension on the mirrored side, I would be extremely grateful.  I took a chance on a company I wasn't too familiar with and for its price, I'm willing to take some issues.  I hope they have an updated set that will have the same dimension going forward.  precision 1-2-3 blocks are next!
