No sir, your nail will not brake.... and the steel will bend.
This attached photo may help.
While not a NOS razor, but you can see the bevel is small, maybe smaller than most full hollow ground razors, the part near the edge is very thin and does in fact bend beyond the bevel under mild pressure form the thumbnail...
Any properly tempered and ground Near Wedge blade will do this.
I must also point out... This is in NO WAY anything like the Thumb-Nail-Test. In this case the blade is held flat against the thumbnail near the edge, and the thumbnail is pushed sideways against the bevel, and you can carefully slide the thumbnail along the length of the edge.
In those days razors were made mostly by hand. Evan today razors are still made by hand by a few manufacturers’. Mistakes can and do happen and it is not unlikely back then mistakes would happen more often than today and a few improperly ground or improperly tempered ("or forgot to heat treat") would get into the hands of customers. It is tests such as this one the customer will have an idea if he bought a good one or a lemon.

Thanked: 156I still don't see how effective that test is. The steel would have to be incredibly brittle or incredibly soft to give a different result.
If you could explain it to me, I am willing to listen. But as it is, I just don't understand.

Even when there were literally hundreds of small companies in addition to the "big dogs" making straight razors after WWII there were still only a few foundries and rht tool steel they all use was, and still is, the same for all of them. As long as it is ground by a compitant grinder and comes from Solingen it shouldn't matter who has branded it. solingen itself - the city brand - has quality specs that are supposed to be made before it can say Made In Solingen, Germany - and so does the Solingen Blade Guild.

Nope! sorry - they are still hand ground by craftsmen. They cost money and have to feed their family too. You are correct that the old american brands and Sheffield brands will give you just as good a shave. It is kind of like going from Miami to New York City in a 1961 Nash Rambler. it is still perfectly good transportation if properly maintained. I am not saying this in a derogatory manor either. A well maintained 1961 Nash Rambler would be a real rarity as are some of the well maintained older razors.

The problems usually occure in the hardening process. Many of the blades warp and some can be "popped" back to their original shape with a dead blow hammer hitting the blank on a leather pad. This usually works; however, sometimes there is a slight twist or bend in the blade that is not at all obvious. they can be made to look like a perfectly good razor and sold as such. This is not done purposfully - it is a QA mistake. Most of the time the twist or bend is so minute it isn't noticed until the first time you go to hone the new razor. If it is slightly bent you will take off metal at the heal and point on one side and only in the middle on the other. This is usually extremely minute but makes all the difference in the world when it comes to getting a good cutting bevel. If the razor is slightly twisted you will take off metal on the point end on one side and at the heal end on the other. As far as I am concerned these razors are pretty much total write offs. They will just never be right. They are rare but these problems happen once in a while to all of them. I have to say I have seen more older razors with these problems than new ones though.

You are correct, but it’s not simply a test for improperly treated steel.
The razor grinder uses it to know when to stop grinding in that area… he will know the razor is thin enough to be honed/maintained easily by the consumer.
It’s the skill and experience of the grinder that makes the difference… too thin and the razor is useless… too thick and he needs to thin it some more until its just right.
I hope that explains
