There are so many good decent things we could make pens out of, why would we want to take a chance of hurting/harming ourselves or others by using something that may or may not hurt someone? I mean we could make pens using the blades out of disposable razors, or we could cast and make pens out of rattlesnake fangs, or tenacles from Man-O-Wars, or barbs from Sting-a-rays. Heck we could even grow a nice bit of mold and mildew, or poisnous mushrooms, and then cast them into pen blanks. If we did, and some child got a hold of the pen, put it in their mouth, bit down enough to penetrate the thin covering, and then got that "stuff" in their mouths, they could get sick or die from it, then where would you be?
IMHO we need to leave the dubious items and potentially harmful items alone and keep this as a positive, ever-growing, expanding enterprise, looking to forward our hobby/business rather than doing things that could have the potential of disastrous consequences.
And that is my 2 cents worth. You can agree or disagree, follow or ignore, or trash to you hearts content. I do not plan on making any additional comments about this.
Thanks
