In this thread, I had questioned the viability of silver precious metal clay (PMC) for use as a pen clip due to its presumed lack of tensile strength. George suggested I do a little research into PMC's strength characteristics and report back.
I had done that some time ago, as I thought PMC might be one avenue for freeing us from kit nibs and clips. My research led me nowhere, however, other than anecdotal references to PMC's weakness due to its inherent lack of density. At George's behest, I gave the research another whack, and came up with an article entitled "Make Your Own Oil Paste" (top of page 5) published by the PMC Guild. While the article does not address the issue directly, you can see that PMC is some darned strong stuff.
Of course, I'd like George to make his PMC clip and tell us what he thinks of its strength, but it appears that, under normal use, a pen clip ought to survive. My next question is, will the threads on a PMC nib survive shearing forces?
