That you see ripped pant legs is one indication of what I was referencing, but perhaps more importantly they can easily take inexperienced people into places they should not be without the equipment or knowledge to continue or retreat. I have seen both "rank" beginners and some with a bit of experience get into trouble with them over the decades. Not knowing the experience level of the OP is why I put the caution in the post. Like firearms, crampons are not dangerous in and of themselves, they are simply intolerant of carelessness, mistakes, and errors in judgment.
