Are MicroFractures a Myth in climbing carabiners? Slow motion break tests on new & abused gear

We bought 6 Mammut Crag Wire Gates ( and 6 Mammut Wall Micro Locks ( to test if microfractures were a myth. We abused 3 of each and broke test all of them on our slacksnap machine. Watch to see if any of them lost strength!

We used a LineScale2 dynomometer ( which is great for slacklines and slow pull tests under 30kn. We purchased all this gear including the dynos but using the amazon links to buy the gear helps this channel out. Thank you Bobby Hutton for filming and helping break test.

Breaking Gear Fear

Edutainment has been a great way to help people understand their gear, and know the true limitations of it.  Watching HOW gear fails is more important than the force itself, as almost all gear is super good enough.  It's more important to share information on how to stay safe than it is to have a paywall.  We hope our stoke is contagious.
