Feather Professonal, Super Professional and Pro-Guard

Price: The price needs to come down to where I have read it has been before, I recall a thread where the blades were $5.99 for the pack of 20, like 2 or 3 years ago. Thats major inflation. With the price lower more barbers and wet shavers would pick up the use of the Feather system. My barbers enjoy when I bring the razor for them to shave me with. With the price lower more barbers could offer the service of a wetshave and still comply with regulation. I hope someone who has control over this is listening. Lower the price increase the number of customers (Supply and Demand) more dollars, pounds, euros, etc.

Quality: First rate as far as quality. I get more paper cuts on my face from these blades than anything else, even paper.

Sharpness: Ok, check this - THERE REALLY REALLY SHARP REALLY.

Longevity: They do go the distance of about 7 shaves, I usually just change the blade every Thrusday.

Smoothness of Shave: OK now here is the rub. The blades are different. They are not equal in smoothness. The Super Pro' blades with there more exposed blades chew me up. I use the same care in shaving and the angles in which they cut is just to steep, causing burn. The Professional blades are just right. From what I can tell, to me when it says coarse (for the super pro' baldes) that means alot of hair on your face not the strength of the hair. My recommendation, if you have to get lets say 60 blades (3 boxes) that will last you at least a year get 2 Professional blades and one Super. Success with the Feather is about the right blade choice. The Feather AC has an angle built in which is compounded by increases blade exposure which leads to less than perfect technique even when technique hasn't changed. The guarded Pro blades are the same as the Pro really, aside from the cage which just lifts the blade higher off your face. The blade exposure (from the Super Pro's) causes your hair to be cut at a different angle and further under the skin, which if your not prone to irritation doesn't cause a problem but for me it does. The Pro' blades are smoother and I still can get BBS or near it with the proper amount of passes - like three.

Packaging: A 1 very simply, very useful. Blade safe at the bottom of packaging.

Note: This razor is not for those who are not confident in there swipes. The Feather will bite you unless you use a nice almost feather brushing across your face stroke. It did me like that for a while, then it clicked - lighten up on the stroke, let the razor do the "heavy lifting" and just guide it. Best of luck.

Aren't these single blades ?

I agree with all your assessments with exception of Pro Guard.
I use this blade with Cobra classic razor and getting excellent shave
