I would like to know the pros and cons of each type of threads for pens. Please discuss...
Here is what I know (or believe) as of this moment, based on my very limited experience:
Multi starts can be a pain in the butt, especially if you have several new pens and can't remember where to position the cap on each one as you close it so that it aligns properly with the other half.
Multi starts require fancy (expensive) taps ind dies.
Multi starts make it particularly challenging to assemble a Little Havana fountain pen, and be able to get the cap to align in both closed and posted position.
So, are there any benefits to balance out the disadvantages?
One negative comment I've heard about a single start pen, the Berea El Toro, is that the cap has to be turned over three revolutions to close. Is that a requirement of single start threads, to need more turns to be secure?
Please enlighten me.
