As the title suggests, bout all the same? Just unscrew? I notice on some pens, where the nib is entered into the section, there are cut outs. Sort of like a keyway. I think Omas has these. I'm thinking a tool to unscrew the nib fits in there. yes, no? Other pens are plain, no keyway cut outs. What's up with that? Do you just grasp the nib/feed and unscrew the nib out? Reading what goes on with, say Pelikan for example, it sounds so easy to swap out a nib. I've never had the nerve to do this.

I guess basicly what I want to know is...Is it as simple as I think or is there rocket science involved?

It is that simple, as for the Pelikans at least. All you do is turn the nib/feed until it comes out.

Hi Green cobra,
#1- always be sure the nib assembly is a screw out kind. Most Vintage pens and some modern pens are a press fit not a screw out.

# 2- on pelikans and other screw outs without out the keyhole slots -- I believe the best procedure is to grip the barrel in one hand and grip the nib between the other hands thumb and a finger and turn the barrel not the nib this prevents to some degree the nib twisting on the feed or the gold being damaged.

My experience is that pelikans are pretty easy. The nib assemblies seem fairly rugged and I have never had a problem removing one. Soak the front end if you suspect dried ink.

#3- if the pen has a press fit nib assembly then you will need a knock out block and prehaps a small brass tube to use as a tap if there is a converter nipple or a breather tube(vintage) you don't want to damage.

Sounds complicated but genrally not too bad. Does depend on the pen type however.

To put it rather bluntly NO!!!!!!!

The Pelikans and some modern pens have screw out nibs, some don't.
Some of the early Sheaffer (Tip Dip) and Esterbrooks have screw out nibs...
Parker 51s are totally different....
Parker 21 differ between the regular 21 and the 21 Super...
Parker 61 are different yet...
Most vintage pens that you find will require making or purchasing a knock out block to take out the nib and feed properly... as they are press fit into the section.

Since my restoration work is primarily on vintage pens, I really can't give you info on most of the moderns....

It's possible that several of your pens work the same way. However, there can be no "in general" answer. There are many ways a manufacturer could install a nib, and most of them have been used on at least a few models of pens.

Any time you want to remove a nib, you have to learn about the particular pen before doing so. Better to ask a question than to find out the hard way.
