I have a Benchmade Mini Adamas and both omega springs are broken. I could send my knife to Benchmade to have it fixed, but I didn't want to wait 4 weeks for my daily EDC knife to be fixed. These feathers are great. The spring deflection of the knives is very light, a bit firmer than the original springs, but that's not a bad thing. I'll get a few more sets in case those springs go away in the future.
