Yes! All of our straight razors are ready for the first shave and definitely sharp enough for that. This statement is based on over 100 years of experience in this business.
There are a few hair tests circulating on the internet that suggest that this is not the case. Such a hair test is not necessarily the best to make a statement about whether a knife is ready to shave or not. A razor is much more about the right combination of sharpness and hardness. Only if these harmonize do we achieve the desired longevity and the required sharpness as well as user-friendliness.
There are many reasons why the first shave with a new knife is not always perfect. These include the angle, the daily form and simply the lack of experience with the new knife. Even experienced razors are not immune to this.
Experience shows that many attempts at repairs initiated immediately after the purchase do more harm than good.
