7 months ago I made thebluedirt's airport proof buckle, wove a belt out of 50 feet para cord for it and have been wearing it for about 6 months almost every day. Late last week it broke.
On the bottom where the hole for the hinge is closest to the wall gave and the buckle fell out. I'm going to thicken that part up 0.5mm (maybe the top too) and go with my 75% thinner one and see how long it lasts this time. All in all 6 months of contiguous wear isn't bad for a plastic belt buckle. I wonder how long it would last made out of the new nylon filament... Maybe I should get some.
