The non-adjustable ones are those plastic ones on for example Speeball and the classic metal ones we can see on most one-type-of-nib holders.
But the reason(s) I created this topic are the adjustable ones. I found these different types: the famoust Hourglass - https://www.paperink...com/hourgl.html, probably even more famous Blackwell - https://lite.cziplee...blique-w-screws and another something on Scribblers - https://www.scribble...blique-holder/. Each of them uses different "mechanism" of holding the nib in place. So, the great question: Have you tried more than one of these types? Are some of them better than others or it doesn't matter?
And which one do you prefer in general? Adjustable or non-adjustable? (This one is motivated by simple observation that most of the obliques are non-adjustable, which I doesn't understand since the advantage of adjustables is quite obvious - you just need one and all nibs you will ever have will fit, so no need for more holders, except for not having to change nibs while working with two at the same time) :-)
Thanks for your answers
