I agree splendid twin victories, casting and turning a great weakness for ever IMHO has always been the skinny amount of material around the nib entry causing havoc for so many pens after a while this detail you employ serves a dual purpose in that this pressure in pressing and in use by the the pen grippers and leaning on now has a cushion for strength combined with a method of assisting the fingers slipping all the way down. Over the years I have spent so much time ie Parents days open days and grandparents school activities as a keen observer of how we handle pens, scary handling techniques abound, chewers and clickers. Commercial pens tend to skinny and tapered heavily to the tip so any and every attempt to change design and strength is to be applauded which I now reinforce and acknowledge. Many members on this site have characteristic designs that would raise shock horror criticism one time a favourite one still is hour glass, centre band, choked shapes in my experience many are sought out at selection time by prospective users.Then to the casting always a revelation how the colours react and flow your blank is delightfully random with pockets of perfection.
Kind regards Peter.:iknow:
