Kai Stainless

These blades are pretty good. From what I have tried there are only two blades are better.
I am talking about Feather and Gillette 7 O'clock Sharp Edge

Not much to say....pretty average as far as my shaves go.....

However, the blades does NOT fit in a 1947 superspeed (only that year with the prongs), which means that either they have not a good QC or they don't make the blade according to standard.

I bought these in the Mustafa market in Singapore.
The price was right. 25 blades for 8 sing dollar.


Quality to me is a combination of sharpness and longevity.

As a reference, I rate Merkur blades as dull, derby medium sharp, my personal favorite Astra Keramik as sharp, and feather as ultrasharp.

I was expecting a sharp blade, something alike feather... however i found the 3 i tried to be duller than Derby. Also I had the feeling the blades deteriorated during the shave. I changed the blade in the middle of the second shave.

So quality overall is low..

Packaging I don't care, else it would have been even lower.

Because of the positive reviews ealier,I will retry these blades later on. If I adjust my ratings, I will let you know, but for now, this is it....

Considering that these blades are made in Japan I thought they would be just as good as Feathers but was I in for a surprise. I have tried 3 blades so far and I wouldn't recommend it to anyone unless you it get for free like in my case.

These KAI blades are absolutely superb! KAI also makes alot of nice kitchen knives and it shows. These blades are wicked sharp, yet not irritating at all. What more can I say? Every shaver owes it to themselves to try these blades. My dad got these for me on a recent trip to Singapore. He paid ~$3.50 US for 5-packs of 5. If I can find these at a reasonable cost, they will be my goto blades. The packaging isn't too good, but each blade is individually wrapped. Also, the blades are free of ANY wirting on them.

I asked our dridiot to send me a package along with my order of 7 oclocks. I figured one box wasn't too many if I didn't like them.

The blades are for me a very mixed bag. The first shave was rough. I experienced a good bit of pulling and irritation. Shaves 2 and 3 were nice and smooth. Shave 4 was obviously the end of the blade and I was right back to a rough, uncomfortable shave.

Compared to my favorite red Personnas these blades just don't cut it, if you will pardon the expression The reds give me at least 6 shaves, and they are comfortable from the first shave. Plus they are a fraction of the cost.

As always your mileage may vary. But if you were asking me which blades to go for if you could only choose one blade, this one sure wouldn't be on the list.

I'll post a review here too. I got a few boxes of these from dridiot as well (Thanks Jason).

These blades are great, but suffer by comparison with the similarly-priced and slightly sharper Feathers. I've gotten great results with these blades in every one of the razors I've put it in. That in itself is noteworthy. I used these blades in a 1940s (notched bar) Aristocrat to shave my head and face; I put 'em in an HD and a Slant, a Fat Boy, a Red Tip SS, a Flare tip SS, a 1948-1950 SS, a 1965 slim-handle Tech, and probably one or two others. I think the best results came from the Fat Boy (set on 3,4, and 5) and the notched Aristocrat. I was very pleased with the blade. It also lasted four shaves easy, and I got five shaves out of a few before deciding I didn't want to press my luck.

The packaging appeals to me because I prefer to recycle my blades in a blade safe rather than storing/disposing of them in an otherwise recyclable plastic case.

But at USD $0.35-$0.40 cents a blade -- and you can get Feathers cheaper than that price from Pauldog--it's a tough sell. These blades might last longer than Feathers, but I still think Feathers are a superior shave by a small margin. If these blades were $0.25 each, I think I'd be inclined to make them my everyday blade.

Out of Japan comes a DE blade not a Feather.

I received these as part of a sampler pack from poster dridiot (Jason).

The packaging, as can be seen, is minimal on marketing. The blades themselves come wrapped in plain paper and the blade has no marking at all.

From my research on this company, Kai (or this division) makes surgical blades. One of their areas is 'blade prep', for which they offer disposable razors. This leads me to believe the company either offers these blades for surgical prep with a DE, or they supply these blades to other companies and don't really put a marketing effort behind them for themselves.

Price: about 40 cents per blade. Does one get what one pays for?

Quality: in my opinion, yes. These are top-notch sharp, smooth blades.

Sharpness: Very sharp, up there with Feathers or Swedes.

Longevity: I haven't pushed these past four shaves; I don't want to risk irritation to find out how long they'd last. But at the end of the fourth shave they are still cutting, not pulling.

Smoothness of shave: can't beat it. I use them in a Slant 39C. No pulling, no weepers, just BBS in three to four passes with no irritation whatsoever.

Packaging: While not long on flash, they have no glue on the paper and I find that a plus. The box is cardboard with no disposal capability.


While these are in the pricing tier with Swedes and Feathers, they are not marketed for mass consumption. They will probably not be anyone's daily blade for this reason; they're clearly harder to come by. I urge those who swear by the above to try these in a comparison test with the top end 'sharpies' and see what you think.

In my opinion, you would not find them lacking vs. the most highly regarded DE blades available.
