Jagen David B40 Safety Razor UK Review 

Thanks for taking the time to read our UK review of the popular Jagen David B40 Safety Razor. At the time of writing this product review, there were over 1,000 buyer online reviews.

That is a very clear indication that this particular B40 model sells extremely well. Primarily that comes down to two key things:

  1. The affordable price
  2. The high buyer satisfaction rating of 94%

In summary this is a double edged head and is 9.5 cm long. It comes with a Jagen David branded mirror travel case. The good news is that the head fits all standard Double Edge razor blades.

All our product recommendations are based on our independent research which we conduct online by reading the many reviews we find at online websites. This review contains affiliate links and we may receive a commission for purchases made.

How Online Buyers Rate the Jagen David B40 Safety Razor

  • On average online buyers rated this with a 94% buyer satisfaction based on over 1,000 online reviews
  • 83% of all online buyers gave this set a full 5 star rating
  • 2% of all online buyers gave this a bad review

The facts are that this one has sold in its thousands. Normally when that happens the review rating starts to drop as more people leave tougher reviews. That has not happened with this Jagen David B40 model, and it remains a huge best seller.

Only 2% of all buyers did give this model a low or bad review. We always like to find out why that would be the case, so we have shown that in the Pros and Cons section of this article, just below.

What Online Buyers Say About the Jagen David B40 Safety Razor

There are usually good and bad points about most of these type of products. We here at the Shaving Emporium prefer to include both of these, so as you have a full understanding.

It is also worth pointing out that some people will always have a moan or a rant, others say it is great and give it a poor rating, and some people say it is rubbish and then rate it highly.

We try and apply a common sense approach to reading reviews. Some of them are clearly left by some strange people, but we have always found that if you look carefully enough, you get some really useful information. It is that which we have summarised below.


This information is based on what online buyers said.


  • Most buyers said this is an excellent safety razor
  • Many buyers bought this as an entry level razor and fell in love with it
  • Any buyer who moved from a disposable to this is very impressed
  • Buyers said it has a really nice weight and feel to it
  • Buyers said once you master the technique you get a great close shave


  • A couple of buyers said it rusted over time
  • A few buyers said the coating came off over time
  • A few buyers said that the razor arrived with the accessories missing


DE safety razors vary quite a bit in price, but we believe that this one is very good value for money. We are also certain from reading the many reviews, that this is a very good choice for anyone looking for an entry level "DE safety razor."
