Dude, knitting is supposed to involve the hands, not the digestive system. LOL I think you need to figure out how to leave the tum tum out of the knitting process. Depending on how something breaks and/or slips, a sharp point could do some damage. I can see it now, Dude quits knitting, he just can't stomach it. Please be careful. I've bloodied fingers with sharp points more than once.
mojo, I have a ChiaoGoo fixed circ and it has stainless sheathed in something cable and it's OK but definitely heavier and not as flexible at the ones with my Knit Picks Options. I also decided I don't really like the ergonomic bend in them.
