The best blade, in my opinion. Sharp but at the same time smooth, without causing any irritation.

Excellent blade, deep shave even with mild machines. Value for money, comfortably used for 5 shaves

Sharp and sweet on the face without irritation. Nice deep shave. It cannot be compared to ASTRA greens and NACET. With ASTOR and MUHLE you achieve the same result but with more passes. With MUHLE R89 razor.

Perhaps the best razor I have tried (about ten well-known brands). The expensive Japanese FEATHER Platinum are superior only in the first shave, but from the second shave onwards, the PERMA SHARP is superior.

Other thoughts:
- I don't know if the DE mentioned in the title implies that it is German, but the box has text in Turkish.
- Alternatively, the Greek BIC, whether the CHROME PLATINUM or the simple red ASTOR that you can find on Skroutz for up to 9 cents each!!! (and by the way, I read somewhere that there are no differences between them, just that the CHROME are exported while the ASTOR are for domestic consumption), you should know that they are far superior to other advertised brands, while in comparative tests they proved to be the most durable of all, providing the best second and third shave compared to any other brand!

I have been doing traditional shaving for 2 years, so I wouldn't say I have much experience.

Serious blade that is difficult to go against the grain. In fact, every time I tried going against the grain, I was extremely careful and still ended up with small cuts in the area where the mustache is, so it's prohibitive in my opinion.

The razor was placed in Muhle R41 Black & Chrome. 2 passes with the direction of hair growth and then again after 5 days. The combination is not for more frequent use as it causes me irritation.

If you take the above into account, this particular blade is ideal for a pleasant and close shave as long as you have the patience to learn it and let it teach you.

They cut and forgive together, they are especially worth it if you make two or three passes in your shaving. Additionally, they last quite a while, easily giving you 4 or 5 shaves and you only throw them away because you don't want to take the risk.

The best there is in blades. It provides a deep shave without any pressure at all, just take them with your eyes closed.

Very good choice for a mild razor!!! I use it with the Rockwell 6c on 4 and I am completely satisfied. No irritation and no cuts.

Stable value, favorite, provides 4-5 comfortable shaves. It is very sharp (not feather but not mild either). It combines very nicely with a mild razor.

Quite a close shave for the mild Gillette King that I use. I did 5 (five) shaves, every three days, without irritation, but with quite a lot of pore openings, hence the specific rating. After a lot of searching for all the above, without the pore openings, I finally found it in Gillette Nacet.

I have no complaints. It is difficult not to get cut a little, but it does its job. I probably need to learn how to use it better.

Very sharp and sweet blade. No matter how much you push it, it maintains its gentle character without causing irritation. It easily lasts for five uses and I would dare to say that its first use is not necessarily the best. Excellent combination with Rockwell 6s on the 4th setting and above.

Quite aggressive blade.. It doesn't suit my skin at all because I shave every day due to work!

Very good blades worthy of their reputation. They are very sharp but will cause irritation if you don't know what you're doing. They are a bit prone to rust (if you forget them for half a day, marks start to appear), but with quick drying, it can be easily avoided.

Finally, a sharp blade that of course requires a little attention. No comparison to the well-known brand that is available in supermarkets.

Personally, I struggled with the blade and managed to have 5 daily shaves without irritations and pulling, except for the fifth one where I pushed it to its limits!
Not bad at all, it costs 1.20€ and comes with 5 razor blades that will last you a month. It is recommended as a basic "tool" that can be placed on the shelf and tested in the next one!

Well, what I have to say is that these were the only blades I hadn't tried before. I believe that in my tough beard, which is very hard because of my job, I have to be freshly shaved every day. I didn't see any difference compared to the Bic Astor ones, they cut exactly the same and they are also cheaper.

The best companion for the Muhle R 89 and any mild razor.

Initially, I dismissed it as unsuitable for my face. However, as a owner of the Muhle R 89, I heard that mild razors require aggressive blades. The result was amazing, as the gentleness of the head tamed the aggressiveness of the blade, providing a deep and high-quality shave.

Worthy of their reputation! They cut easily without needing much pressure, resulting in no cuts or irritations. With my tough beard, the double-edged razor blade gives me 5-6 very good shaves or 2-3 with a half-blade on the safety razor.

Use with Merkur 23C. Brand new in DE. My first blade with daily use. So far, no cuts or irritations. Not very aggressive

The Perma Sharp blades are sharp but not aggressive. They never leave me with cuts or irritations - not even on the neck.

The rating that follows is based on the following data: I have tough beard and shave every 2nd or 3rd day, always use pre-shave and use tallow-based soaps. The razor is Merkur Slant 39c.

Aggressiveness/Sharpness: 8/10
Smoothness*: 9/10
Sharpness Duration**: Up to 3 shaves.

* I evaluate smoothness during the shave (if the blade doesn't stick or tug, then it is smooth). I do not evaluate the smoothness of the end result since with traditional shaving, you can always achieve a smooth skin (BBS).

** I do 3 passes with each shave.

It is my second favorite blade. Although one time I forgot it in a machine for three weeks, it had rusted

Honest blade, predictable, forgiving of hasty movements. In my Muhle R41, I would describe it as very reliable. I will buy it again for everyday shaving. It may struggle with a close shave

Although subjective, the blade issue starts with the obvious.

One of the sharpest blades along with Feather.

If you have an aggressive razor and you are a beginner or have poor technique, the only sure thing is that you will cut yourself and have irritations. It's not the blade's fault.

In the first shaves, I had irritations, but after a few shaves and with caution, I have amazing shaves with these blades, just like Feather.

P.S.: I use the rockwell 6s

Excellent! They stand out from the rest that I have purchased. Very good blades and a good value for the price! I will buy them again!

I think it is the best blade I have used so far for everyday close shaving.
Very sharp, it doesn't pull or irritate.

Top razors. Very sharp, give a close shave. Be careful if using aggressive machines.
