The
metal one is what many professionals use to open iPhones, iPads, and
cases that require more leverage or a sharper tip. It's handy for cell
phones, laptop's, glued LCD screens, and other plastic electronics. This
is made of metal so it is stronger than the plastic tools, so you have
to be more aware of possible scratching. Approx 7" long and polished to avoid scratching.
The nylon and plastic ones are what most Apple professionals use to open iPods, iPads, iPhones, cell phones, laptop's, LCD screens, automobile lights and covers, other plastic cases and small battery removal. The flat tip is 1/4" wide. It is heat resistant reinforced nylon and a handy solder tool. There's a notch near the flat end to catch and bend small wires.
I have other quality tools including sets of multiple tools and wholesale quantities, check out my other listings or eBay store.
