I would like something secure (preferably locking) and not made using cheap labor but I can be flexible. Obviously the keybar magnut isn't locking so I'm here exploring other options. I didn't go with the nite ize nite binder because I hear those aren't durable. I've looked at carabiners but either they're not locking or too big.
So far the best contenders I've seen is the keybar medium Magnut which has about 18lbs of pull forcem
I was looking for a small connector to my keyring to my paracord bracelet. So I'm looking for something similar to a high quality buckle or something similar.
from the page: "1,000 lb. load-bearing buckle" and "PROUDLY HAND-CRAFTED IN THE USA" This is likely the closest thing you're going to get to meeting your stated criteria.
Yeah it's definitely at the top of the list for now. I've also been looking at just the buckle itself, as I don't need the strap part of it.
