Flex in the Waterman sense does not exist with Esterbrooks. Flex compared to a nail does but that isn't much.
A lot of the nibs need to be tuned out of the box but if you use it a while it should get better. The other option is to go for the 9xxx series nibs.

I guess "flex in the Waterman sense" isn't what I want. The Esterbrook 2048 is flexible enough that if I just write with it, the writing screams "you can't do this with a ball point pen!" That's what I want. I don't want calligraphy.
How would I go about "tuning" it? Is that different from grinding? I gather from another topic that regrinding an antique point is destructive, or heretical, or blasphemous, or something like that, my aging mind can't find the exact word.
As for the 9000 series, I gather from other topics on the web that they were hand finished and therefore somewhat variable, and that machine-made nibs are more consistent. Now, maybe I'm misunderstanding something, and the 2000 series nibs are also hand-finished and therefore variable. But I thought the reason to buy 9000 was durability rather than consistency, and at any rate they would be no more consistent than the 2000 series.
Back to the point: there's a top view of the 2442 (compared with another nib) at
http://www.fountainpennetwork.com/forum/in...9&pid=92498and a side view at
http://www.fountainpennetwork.com/forum/in...9&pid=92499and I can see (by rotating one picture and superimposing it on the other) that the blob on the underside is longer than it is wide. So I don't understand how it's supposed to work, and in fact it doesn't work when I use it.
Could I hear from somebody who has experience using the 2442 and can tell me if I'm doing something wrong? Like, I'm looking for the sweet spot in the wrong place?
Hmmmm, I remember those photos...

Tuning... the act of improving the writing behaviour of a nib by adjusting the alignment, smoothing the tip and perhaps adjusting the ink flow to suit the user's particular writing style and grasp of the pen.
The estie 2xxx nibs were 'folded tine' nibs, and somewhat scratchy out of the box. If yours is new, it's likely in need of smoothing (that's the better term for finishing a nib by polishing than grinding). The disdain you've noticed about 'grinding' - well perhaps not exactly distain, but advice against it is based on the fact that the folded tine nibs won't take much actual metal removal before the fold fractures or separates and you basically lose the nib, but they can be smoothed using fine abrasives. Refer to the pinned articles at the top of the Repair forum for information on both grinding and smoothing.
The 9000 series nibs are tipped and can be ground as can any tipped nib. The 'heretical' aspect of such action exists only in the mind of an obsessive collector, particularly wrt Estie nibs, and needn't be worried about further unless you intend to hover amongst such people.
If your nib has been used, it's likely that it is worn to the hand of the previous owner and may not work well for you. It will certainly need some of the 'corners' removed if badly worn. And don't be surprised if a tip falls off if there is a lot of wear. They were actually made to be easily replaceable, and probably were considered disposable.
Examine the tips carefully with a loupe. If there is misalignment (the two tips aren't at the same level when viewed from the end - or just below as if looking up from the paper) that has to be corrected before proceeding - it may cure the problem by itself. If that doesn't work, try smoothing the corners of the nib point - the outside edges first, and the inside edges next, using a fine grained film (1-0.5 micron perhaps). Actually, you should try to determine the direction the scratchiness appears - ie moving to the left, or the right. If the nib catches when moving to the right, then you have to smooth the outside right side of the right tine, and the inside right edge of the left tine.. etc...
Not sure of your question regarding the shape of the tip.
As Todd says, there's some variation from nib to nib out of the box, and it's not unusual to have to do some work - even on a NOS nib to get it to feel really smooth. If you don't want to try the smoothing yourself, there's many on the FPN who could help you out.
