Chris,
May I offer that I feel that there is a bit of a cultural disconnect between yourself and magnus. What I mean is that, culturally, we Americans are largely (though we compulsorily deny it till we're blue in the face) concerned with how we will come across to other people, whereas, Scandinavians and Germans, in General--throughout this post, I will only be speaking in the widest generalities--are largely concerned with finding out truth. One way of finding out truth, (I've tried this btw, many times at work) is to make the biggest ass out of yourself that you possibly can, just to see if you can irritate anyone enough to work up the muster to try to refute you. It works, but I don't think that this is what Magnus is doing. He's simply stating that his chains are incredibly, sharp: sharp enough to cut a fingernail, and that he has frequently used magnification to examine his edges, and from these statements, the poor man, who is using English as a second language, has to encounter any amount of bluster from you and Jay and other Americans, like me who insist on treating everyone around here with kid gloves. (There, there... I'm sure we all have something valid to offer... etc.)
Now me, on the other hand. I can be pretty tough over the internet. If I were there with you in person, I'm pretty sure that I would be a super nice guy, because you could kick my ass. With Jay... the same. Over in Sweden with Mag... the same. However: if the three of you care to come over to Washington for a good ol' redneck cookie cutter... my square filed chain will kick all of your round filed chains asses, and that's that.
