Klinknagel-veerclip

The spring tension on this clip is just right—firm enough to hold a case shut but not so stiff it fights you. Riveting it on took a few minutes, and now the retention on my tool pouch feels rock solid. Exactly the permanent fix I needed.

Riveted this onto a leather holster I finished last week and the clamp tension is seriously strong, no wobble at all. The rivet holes lined up clean, which saved me from drilling new ones. Feels like it'll outlast the leather itself.

Wasn't sure a spring clip would hold up on a case this small, but the rivet attachment feels rock solid once it's set. The spring tension is stiff enough that nothing's popping loose, and it sits flush against the leather instead of digging in.
