Here are mine. Everything is U.S. made except the 3 Knipex pliers. It might be hard to see, but the all metal one (without colored or riveted handles) is an older Snap-On that I found a couple weeks ago at a garage sale for $2

. All it needed was a little hinge lubrication and now it is up and running again.
The Lang kit was purchased about a month ago, so I haven't used it yet to know how nice it is in action. All the tips look to be shaped and aligned correctly and of general good quality, so I don't expect to be disappointed.
Now that I have a full kit, all the interchangeable head snap ring pliers will most likely end up loaded with custom tips for specific tasks and then left that way. I make custom tips by grinding down nails etc. and screwing them into the pliers as needed. I have a couple small flat "duckbill" style tips (made by grinding down finishing nails) that come in handy a few times a year for releasing small c-type snap rings.
The Knipex snap ring pliers are my "ugly ducklings", because they almost never actually get used for snap rings. I originally purchased all 3 of them for use as straight, angled, and 90 degree round nose pliers. I planned on grinding off the snap ring tips, but I found they didn't get in the way so I left them just in case I ever needed them for actual snap rings

. Round nose pliers are hard to find in any decent quality, and when you do find them they are straight only and quite expensive. 95% of the time I use them to make things like terminal screw loops in solid copper wire or for working with Tygon fuel lines on small engines. They can reach into tight areas and grab quite well without damaging the soft Tygon fuel line. I only reach for my larger and more bulky needle nosed pliers (with partially smoothed out teeth) if the fuel lines are really stuck.
