Just like the thread title says.

I was doing some FoF and got blown into a park bench where my Spyderco Street Beat sheath got hooked just right as I fell down backwards. Scratch one G-Clip but the sheath looks and works good as new.

You want a quality sheath that can take a 250 lbs man full-on falling with shearing force on the rivets and come out smiling, you need to get yourself a sheath from Invictus Kydex.

'Nuff said!
