Nite Ize Stainless Steel Size #3 S-Biner

Perfect everyday tool!

I used the size 2 to carry a Fisher space pen on my belt loop. The pen was attached to the carabiner with an o-ring--the old fashioned kind you have to wrestle around 3 times. Much to my amazement, after a day of mild hiking (no slithering through tight spaces), the pen and o-ring were gone. Empty carabiner on my belt, apparently with no damage, still springy. The only way for houdini to have escaped was the s-carabiner opening. Bad luck. So i bought another S-carabiner and another space pen. And two hikes later, the same thing happened! I'm changing brands because i don't trust the flimsy looking locking one either.

I have used these for a while. I bought the slide lock one and lost one of the slides. Wonder if I could purchase. Other than that I love these.

just bought the two pack size#1 one broke as soon i tried to use it the locking piece come out so i cannot lock it
