Many years ago, I had a Chris Reeves SF knife. We crammed too much stuff in a very large Pelican Case. It wouldn't open. I tried to pry it open with my knife. The knife snapped. I was only using my hands on the knife.
I researched. I found the Scrap Yard after finding Knife Test.
Yesterday, the same thing happened, almost. The case holding my satellite uplink gear wouldn't open. We pulled and kicked. No use.
I wedged my Wardog in there. We took turns pulling and pushing on the thing. Even the big Marines couldn't open it.
Don't over stuff a Pelican case like a suit case where you have to sit on it to close it. Especially with hard items.
Bullet meets the meat time. I crammed the Wardog in again. Then I stood on it. I bounced. The case opened. Blade is still true.
