I was wondering if this tool was used for some other purpose first, maybe without the coated jaws. The cost is so low, it would seem not to be a pen-hobby specific tool.
I’ve googled quite a bit, searched Amazon, and looked through the mega pliers thread here (nope, didn’t click all the links!), to no avail.
Being a pen Turner myself, these are on my wish list. Worked in many different industries but can’t remember seeing these before. However, I can imagine securely griping small delicate tubular materials they could be useful.
It looks like that, but I’m surprised they’d be selling them so cheaply. It seems labor intensive for a presumably low-volume item that I’ve seen sold for as low as $11.95. You figure there is labor, two sets of shipping, and two sets of markup in there, too - after the plier and dip material cost.
While there is more time and labor involved in attaching the special jaw attachment, maybe there is time and labor saved in not having to finish the jaws’ inner pliers?
One could always use square tubing and a dip-coating to create jaws for standard locking pliers, these are cheap enough where DIY might not be justified, at least not to save money.
