Well, where or who you got it from should answer that question. If you got it from and experienced wet shaver that is proficient at honing then you are most likely good to go. On the other hand if you got it from someone that is not known to you to be an experienced person then it get questionable. Amazon, Ali Express, and Ebay are not always good sources for beginner blades. There are quite a few places you can get shave ready blades from. Knowing where you are from would give me a hint as to whom I might recommend.
