Three stars for being square, as far as I can tell, because you need a square to check a square, assuming the square you use to check the square is square, which you need yet another square to be sure, and how do you know if that one is square to check all the other squares against, if one or more manufacturers lose sight of the fact that as Brad Kennedy noted, when you need a square, you need it square. Just like you need a ruler or tape measure's inches to actually be inches, but how would you check that, except with another, but what if that one wasn't accurate, either, and so on and so on... BUT... Two stars off for being the first-ever try square I have ever seen or heard of that wasn't calibrated in inches, or any other measure, AT ALL... Beautiful tool,...

 I recently purchased these turning tools on sale and was very disapointed. While they appeared to be of decent quality, the cutting edges were not very sharp and required that I sharpen them right out of the box. I would suggest you spend a little more money and buy a better set.

I bought this set around Christmas, also recommended by a store employee.They sharpen easy and hold a edge well I've turned quite a few pens and turned some bowls that were from very dried out and hard wood. I have no complaints they perform well.

By far the best tool purchase I've made in a long time. I find myself using these three tools the majority of the time. Not only do they cut extremely well & easy,they feel great. For the money you won't be dissapointed.
