Personna Comfort Coated (Lab Blue) – AccuTec Blades - USA
Personna is one of the brand names used by Edgewell Personal Care. We have already reviewed the Personna Platinum Chrome blades currently being manufactured in Germany. However, there are two Personna blades that are still being manufactured in the USA by AccuTec Blades based in Verona, VA. This facility was once part of American Safety Razor and was spun off from the other blade manufacturing facilities when Edgewell acquired the company. The Verona plant primarily produces blades for medical, scientific, and industrial uses. The Personna branded blades are produced under license. While razor blade manufacturing used to be widespread in the USA, AccuTec blades is the sole major producer remaining.
Two of the AccuTec DE blades have become popular among shavers. One is the Personna Comfort Coated blades that are sold for laboratory use. They are affectionately known as Lab Blues. The other are Personna blades produced for medical/hospital use. They are known as Med Preps.
I have tried only the Lab Blues. The Med Preps blades are far more expensive than the Lab Blues. Some say the Med Preps are superior to Lab Blues and are well worth the premium price. Others say the only difference is that the medical use blades go through extra cleaning and sanitizing steps. If anyone has used both these blades and wants to comment on this controversy, please do so.
The primary design feature of the Lab Blue blades is the “Comfort Coated” polymer coating. While this coating does make the blades quite smooth out of the wrapper, the thick coating also impedes the cutting performance of the blade. For those who do not have tough beards, this might not be an issue. The blades get significantly sharper as the coating wears off, but this is at the expense of smoothness. This makes these blades difficult to evaluate.
I started this morning’s shave with a Dorco Prime Platinum STP301 blade in the Karve C-plate razor. That blade was on its second use. I took a few strokes and found the blade to still be sharp and smooth. At that point, I replaced the Dorco blade with the Personna Lab Blue and completed my shave.
The first few strokes with the Lab Blue blade revealed some tugging on the 1st pass WTG with my two-day beard. The blades were similar in sharpness to a new Astra SP blade. By the 2nd pass, the blade no longer tugged. During the course of the shave, I could tell the blade was getting sharper and less smooth as the coating wore off. By the time I got to my clean-up pass, I even got a weeper, something that has occurred only one other time during this evaluation series. By this time, the blade was sharp enough to get a near-BBS shave, but at the expense of irritation.
When I applied witch hazel after the shave, I got significant stinging. I needed to use an aftershave balm to soothe my skin. I normally do not need a balm except when temperatures fall below 10F and the humidity is low.
During the shave, the sharpness started at 3 and increased to 4.5. At the same time, the smoothness decreased from 4.5 to 3. I feel compelled to rate the blade 3 on sharpness and 3 on smoothness as I got some tugging on the 1st pass and significant irritation during my ATG and clean-up passes. Had I been content with a DFS rather than pursuing a near-BBS shave, the irritation would have been less, but I would not have been happy with a DFS since I am only shaving every two days.
I have added the Lab Blues to the spreadsheet.
I was initially planning to use the blade for a 2nd shave, but due to the irritation experienced on the first shave, I decided to end the evaluation. I know from previous experience with these Lab Blue blades that on the 2nd shave they will be similar in sharpness to the Personna Platinum Chrome blade (4.5). However, the Platinum coated blades are significantly smoother. Unfortunately, due to the significant change in sharpness and smoothness of the Lab Blue blades as the coating wears off, I cannot recommend these blades. However, I know there are those who love them. I suspect they do not have a beard as tough, nor skin as sensitive as mine. I do recommend the Personna Platinum Chrome blades whether they are the older Israeli Reds or the current German Golds.
The Wilkinson Sword Classic blades made in Germany tend to exhibit similar characteristics of the Personna lab blues. I might try to evaluate them later in the series, but I tend to avoid them because I do not like the significant change in sharpness as the coating wears off. If you are not careful, you can end up with weepers and irritation as I did during today’s shave.
The next blade to be evaluated is one of my all time favorites, the BIC Chrome Platinum. However, some people hate it as it can be too sharp for use in some razors.
