I was wondering if anyone has used these? Pros and cons? They look like they are made out of steel or another heavy metal. I was thinking I could have the local machine shop make me a custom pair out of magnesium if they work well for use with 3/16" diameter spyderline. I would do it my self but to many dangers machining magnesium. The magnesium ones would be extremely light and also double as emergency fire tinder in a survival situation.
This also makes me think to make a extremely small pair to work on guylines for my tarp.hhhhhhmmmmm.....maybe one out of ferrocerium rod.lol
