I just listed these pliers on Ebay, and I have not seen this logo before. It looks like an OM inside a diamond or possible a DM.
Thanks,
John

Wild guess....The Douglass Manufacturing Co., Seymour, Conn
(I can't find an example of their mark anywhere, but they did make mechanics tools, including pliers...)
Edit: On further info, the company may be too early for that style of pliers
Why not Diamalloy, Diamond Caulk horse shoe wrench. From Minnesota.

I thought of them too. But I can't say I've ever seen that logo before, nor have I seen Diamalloy referred to as DM...Diamond Manufacturing maybe? Doesn't sound right. Diamond had some pretty famously cool logos, if that is one of theirs, it's a 'not famous' one. I'm thinking it is something else.
Looking at it some more, I think now it is DM. I will look in my EAIA Directory for possible companies.
I wonder if you should send an email to hmboo. I suspect it's European.
Domestic Machine Co???
