The info wore off the grip and I do not recall what it was. I think it was a German brand. These have been one of my favorite tools for a decade. The jaws are much more narrow than what is typical for side cutters and these handle like a surgeon's scalpel. Best of all, they can be sharpened many many times. Unfortunately, these are getting close to end of life from all of my sharpening and pivot pin wear. I want to get another set, but I have never been able to figure out the brand to find them again. They were given to me by a tech for a computerized Guru bicycle fit machine we had installed in one of our bike shops in 2012.
Also showing up a couple places as the brand "Marubi"
"Best tool co ltd" both sounds like it could be some generic no-name brand, or an OG manufacturing titan who still makes stuff that lasts. The brand sounds vaguely familiar to me, but more googling isn't bringing anything up... I might be remembering Festool, which conveniently rhymes with Besttool.
That's what I suspected with the name, and I tried to do a little poking with some translators, but it wasn't really working as I had no understanding of the correlation between the syllabic spelling vs the hiragana. Thanks for the little breakdown!
