Awesome, just not for climbing
This knife is awesome, I only wish it had a saw. Also, I have yet to ever use the little hook thing on the back.
That said, despite the name, THIS IS NOT A CLIMBING KNIFE. Please do not use it as one; it is an excellent knife, but simply awful for climbing.
A good climbing knife should have:
A serrated blade
A locking blade
Good attachment point
Buy it, but don't take it up the wall with you.
