    This is a review of the nib itself, rather than the unit. I ended up switching the feed out for one that worked better in my extremely specific circumstances, but I don’t suspect this to be a common requirement for most people.

    The nib flexes well and snaps back quickly. The upper bounds of how wide you should flex the tines feel very intuitive, so it’s not likely that you will exceed that width unless you’re really gunning for some fat flex lines beyond reason.

    The tines flex very easily, so even though with zero force you can still write with it as an Extra Fine nib, it’s more likely that with the tiny amount of force exerted by normal handwriting, that you’ll probably be closer to writing as a Fine nib, or at the very least seeing some parts with Fine line variation.

    I do think the cross-cut flex style of nib does require even more proper technique than a standard flex nib, because if your angle is off by very much, there’s a chance for the tips of the tines to overlap slightly. This is more of a user-error issue though, and not a reflection on the quality of the nib itself. I’ve only had it happen to me while writing quickly with lots of line variation. You should be more impressed by the fact that this nib lets you write quickly with lots of line variation than off-put by the fact that if you mess up while doing that, the tines can overlap.

    This is definitely pricier than most other modern steel flex nibs, but there are also less issues. Five stars.

    If you’re wondering if you should get it. The answer is yes. Yes, it’s that good. Just get one. Get the eyedropper setup and try an Opus 88. It’s divine.

    I have the rare 1.1 Stub Secretary of de Flex, it is FANTASTIC. I have a dozen modern nibmeister flex nibs, and this might be my favorite of them all! With non-flex writing it’s incredibly bouncy and juicy, with barely any pressure flexing it has insane line variation from the stub/flex combo. I’m never not going to have this nib inked!

    I really like this nib grind. It is VERY wet and flexes effortlessly. I am learning how to write with such a wet nib but the work Kirk does is outstanding. I ordered anther grind from him and I’m equally impressed.
