Like Feather, these are made in Japan, but they’re not as well known.

1st blade > 1st shave
Truefitt & Hill No. 10 Shave Cream

I had shaved the day before so took it easy. There wasn’t much stubble so no surprise that I had no tugging. The only nick I picked up was the re-opening of an existing scrape. The shave was nice and the finish was pretty good but by no means a great shave.

Wet Shaving Products Vetiver Rustic Shaving Soap

The blade easily sliced through my stubble without any tugging or effort. I did pick up a few nicks around the edges as I tried to get the perfect shave. The end result was generally very good, with a couple of areas getting close to BBS, but these were balanced by some rougher patched. Still a very good shave.

1st blade > 3rd shave
Dove Men+Care Sensitive Shave Cream

Despite using a brushless cream, I encountered no problems save a little clogging. The blade didn’t tug and I was left without irritation. I did pick up a couple of nicks, but these were either outside the lather area or were re-opened from the previous shave. Brushless shaves are never as close as a proper one but the end result was still adequate.

Yeti Snot Shave Soap

The blade didn’t tug but it did cut me up. I had quite a few nicks, a few of which survived past cold water. The slickness and lather from the soap wasn’t great, so certainly didn’t help. I also had issues with my brush, so the protective layer applied wasn’t as good as it could be, but still more blood than there should have been. And yet, the finish wasn’t particular great either.

Boots Freshwood Brushless Shave Cream

The blade didn’t tug and I was left without irritation. It did get clogged a fair bit, but that was due to the cream. I picked up a couple of nicks, but these were sealed before I finished shaving let alone got to cold water. The finish was excellent though, with minimal resistance and a few places got close to BBS.

Taylor of old Bond Street Jermyn Street Collection Shave Cream

I thought I had a little bit of tugging on the first pass, but it was so mild I wasn’t sure. Aside from some clogging, I picked up a couple of nicks, though nothing serious. They were all sealed by the time I got to cold water. A really excellent shave with a few places reaching BBS.

2nd blade > 3rd shave
Yeti Snot Shave Soap

No tugging on this use and very smooth throughout. I had a couple of tiny nicks, with one just about surviving past cold water. There was some resistance and a little roughness in a few spots, but the finish was generally smooth. A good shave.

2nd blade > 4th shave
Art of Shaving Lemon Shaving Soap

It didn’t tug per se, but neither did it slice cleanly. It felt rough and left me with a ton of nicks, albeit small ones. Most were sealed by cold water but a few remained afterwards. The end result wasn’t bad, but certainly didn’t blow me away. Marginally above average.


I’d not heard of these before, but Japanese blades tend to be highly regarded, such as the legendary Feathers. I was also expecting these to be sharp.

The number of nicks I picked up suggests they lived up to my expectations, but the finish rarely wowed me. So all the negatives with few of the positives.

They’re pretty expensive on a per-pack basis, so these needed to be top-drawer, and that they weren’t. They didn’t seem to have a lot of legs either, with the fourth and final shave on both blades being a bloodbath of roughness.

They do the job, but there are better blades out there, and for less money.
