Proving his world class grip strength, Sheldon Trefenanko has just certified on the Captains of Crush (CoC) No. 3 gripper.

Trefenanko is on a roll, having just certified on the Crushed-To-Dust! Challenge last month, and now dispensing with the legendary CoC No. 3 in a dominating display.

“This is something I have been after for a long time. It’s a great accomplishment for everyone that belongs to your lists of all of IronMind’s challenges [certifications]. I encourage everyone to give it a try and challenge yourself. Most people don’t understand the strength it takes to accomplish these feats. I am very proud to be a part of it and will keep promoting it to all my friends and family,” Trefenanko told IronMind.

Here's a video of Sheldon Trefenanko destroying a Captains of Crush No. 3 gripper on his official attempt to certify.

Congratulations, Sheldon: it’s official and your name has been added to the official certification list for the Captains of Crush No. 3 gripper!
