Switch Kai and Feather in this sentence and it would describe my experience. YMMV

Feather for me. Kai gave me the tuggiest shaves I've ever had.

I have both but have not tried the Kai's yet. I hope to use one tomorrow. I really like Feather blades though so hopefully the Kai blades will work out. I know they cost quite a bit more than Feathers so probably not "worth" the extra money over the Feathers.

I just shaved with a Kai for the first time tonight. Fabulous shave with my R41. Smooth and sharp.
However, I voted Feather because I have used them extensively enough that they are a known quantity; I only have one shave on the Kai.
But....
After the shave I just had, knee jerk reaction? Flip a coin. It's that close.

For me Feathers hands down!! The Kai blades feel thicker in hand and I can also feel that through the shave.
The edge wasn't as good as a feather and didn't have that same sharpness.
Now I don't know the thickness of each blade or what the difference would be at the edge, but it feels like the feather is a thinner sharper edge to me!?!
Of course that could completely wrong hahaha but that's how they feel in use for me

I have been using Feathers for years, among others, and only just tried the Kai when a friend sent a 5 pack. So two blades in on the Kai and I'd say they are equal to the Feather in sharpness, and maybe a tad smoother. I'd rate them both the same on my particular face/neck. OTOH, I need to try more examples of the Kai to be certain.

Only 6 months into DE shaving but for me it's:
Kai - clearly better/smoother
Feather - second best
The other 8 I've tried so far - noticeably less sharp/smooth/comfortable than the two above

I want to like Kai's because they are slightly wider than other DE blades.  In my head, I feel they should offer a little more aggressive shave.
But my reality is that Kai blades are a little on the rough side for me.  Feather blades always give me a nice shave. 
Oh sure, I'll get the occasional rough 1st shave.  But on the whole, QA control seems to be top notch.

I think that if you put a KAI blade on top of a Feather blade, or put a Feather blade on top of a KAI blade, and line them up, you will find that the two blades are the same width. The KAIs are thicker (heavier gauge) than the Feathers, and the Feathers have a very slightly larger diameter of the round holes in the blade than the KAIs do.

Kai for me too is a better performer. As already stated by some, KAIs are stiffer and thicker comparatively and hence for me is a lesser chance to cut myself. I do use a Shavette once in a while and Feather always give me a few nicks but KAIs, never.

Kai blades are not unusually thick blades as measured by micrometer, or by Kai's published specifications. Urban legend. T=Thickness below. .10mm = .003937"


[Image: baee3215d2e823c391f01b6b9f300a66.jpg]

And:

Gillette Silver Blue 0.0038"
Gillette Astra SP 0.0036"
Gillette Super Thin 0.0040"
Polsilver Super Iridium 0.0036"
Iridium Super 0.0036"
Polsilver Stainless (russian) 0.0040"
Personna Lab 0.0041"
Personna Med 0.0041"
Rapira Platinum Lux 0.0039"
Rapira Swedish SS 0.0041"
Bolzano Superinox 0.0041"

Thus 8/17 other blades measured are as thick as the Kai.

Published specification is equal to micrometer reading:

Just received 20 five packs. Shaved with one 5 times now. Two pass shaves. My usual is 2-3 shaves with other blades, Feather included. To me they are as sharp as a Feather but smoother, longer lasting. YMMV.

At some date early last year (2016), I decided that henceforth I would purchase only KAI and Feather blades, and, for more than a year now, I have been alternating between KAI and Feather, using each individual blade until it told me that it was time to change it (typically, five shaves for a Feather, and seven shaves for a KAI).  Familiar as I am with how a blade of each brand feels between the fingers when I insert one into the razor before a shave, and how it feels between the fingers as I remove it from the razor for cleaning after every shave, I was convinced by tactile feel (redundancy alert) that the KAI blades are fashioned from heavier stock than the Feather blades.  Moreover, whereas both the Feather and the KAI perform well in the Feather AS-D2 razor, where the blade is tightly clamped, top and bottom, in the iKon Deluxe OC razor, where the top piece is the same as in the Feather, but the baseplate gives the blade less underside support, the Feather exhibits considerably more judder than the Kai does.

The statement of jmudrick above, therefore, gave me pause.  (I wished that it had cited actual sources that could be followed up, such as where one could access “Kai’s published specifications.”)  So — although I have an inexpensive vernier caliper, I lack a precise micrometer — I conducted a dead reckoning, or “Kentucky windage,” experiment to see if I could either verify or refute jmudrick’s summary dismissal of the conventional wisdom that KAI blades are thicker than Feather blades as an “Urban Legend.”  

In my blade bank, I found that I had 22 each of Feather and KAI blades (used, of course).  Eyeballing is aided with a greater scale, and so — not without difficulty, because the blades seem to have an aversion to being stacked neatly, and one must exercise great caution when grasping the blades by the edges — I stacked 22 blades of each brand next to each other, and photographed the stacks:

[Image: 0PUhdzH.jpg]

To my reckoning, the two stacks appear, if not identical, then very near to identical, in height.  There is no basis from visual inspection of stacks of 22 units of each blade that the KAI stack is taller than the Feather stack, which it necessarily would be if the KAI blades were significantly thicker than the Feather blades.  

I reach the tentative conclusion, then, that the tactile difference in stiffness between representatives of the respective brands of Japanese razor blades must be due to factors other than the thicknesses, respectively, of the two brands of blade.

I've previously posted these, though perhaps not here, so here you go.

Where T=Thickness in mm

Kai blade specs:

https://www.kai-group.com/global/en/biz/...ecial.html

Micrometer measurements (consistent with Kai specs):

https://www.badgerandblade.com/forum/wik...ions_Table

GSB, Dorco, Nacet also measured as same as old Derby (which is same as Kai) here:

https://www.badgerandblade.com/forum/thr...ss.473253/

The conclusion being that while there are indeed blades up to .01mm thinner than the Kai, there are many, perhaps the majority, which are equal in thickness.

To me both Feathers and Kai's are highly Overrated 
Blades and Polsivers SI and 7o'clock Blacks are far
Superior to either..
