Kai X Seki Mago Roku Finger Nail Cutter with Nail Filer

The finish

But large if you have small hands, but t excellent quality as expected from all Kai products I have knives from them

After doing a bit of research, I couldn't decide between this one, and another above average Japanese made nail clipper. The reviews initially of certain Japanese made nail clippers seemed to suggest they're quite a bit better. Though it's hard to say, time will tell. However, initial impressions after a few uses, is that the tolerances for a good cut may be slightly better than all of my other nail clippers. They do seem to cut more smoothly, resulting in a less sharp feeling of the nail - needing less filing afterwards to remove any sharper edges. I even keep my other nail clippers sharpened with a little maintenance, but none of them cut as nicely, so maybe there is something to it. If you figure your typical set of clippers costs ~ $10 at a box store, or you need to pay 3X as much for a pair that does a better job, you probably would save a bit of time in the long run not having to spend as much time filing your nails. Both pairs of Japanese clippers I bought do share one aspect I've found more impression - the build quality. The tolerances for how everything comes together, the mechanism, the way the pressure is applied, it's obvious they are built better - both seem to be engineered slightly more, using thicker metal stock, or designed with gussets to improve the rigidity, and resulting in a more "solid" feel.

originally blades were a little too sharp and caused a bit of nail sharding, but after a few times of use, they became perfect, cuts perfectly every time with no negative effects.

Works really well, best nail cutter I have experienced so far. It is expensive but will be worth the money if it can last for for at least a decade (last I used was from scoll and it good but lasted only for 4-5 years.

Seki City, Japan has been known for high quality knives since at least the 1980s, the successor to Solingen and Sheffield. I have several. So it's no surprise that these are outstanding. As for the "samurai" thing, the best katana blades were made in Bizen, a region just to the west, but I can't blame KAI for marketing :) They of course have nothing to do with tamehagane steel used for sword blades. I had just done my nails prior to receiving it, but clipped a bit of thumbnail to test them. As described in other reviews, it cuts cleanly without snapping off a piece, and it doesn't fly across the room. Very sharp. They are larger than most fingernail clippers, but this is a huge plus in my book. Using my left hand to clip the nails of my right is a huge pain with little clippers, as I'm right-handed; and sorry to say my left hand is pretty inept. These have the sharpness, purchase, and leverage to make it a breeze. My nails are thick, I've often used toenail clippers for them. Don't know how some people find it "too bulky to use", it's great. Requires very little force. I also like the gentle curvature of the blades. So many clippers seem to have extreme concave edges that are fine for a pinky nail, but way too curved for a man's thumbnail. These are just right. The nail file slot thing is okay, but I'll never use it. Have German sapphire files for filing. Could be used in a pinch. In short, highly recommend. If your toenails aren't thick you could likely use these for those too. Especially for the price paid, these are excellent. Very good steel.
