In reply to Bob_the_Builder:
Never had any front points bend and including all my hire crampons, I have had over a dozen pairs in constant winter and alpine use, for well over decade.
I have had the odd lower points bent slightly from stumbling over rocks.
I can see how it would be possible if you jammed the points in a hairline crack and levered it when standing on it!!
I like the Grivel kit due to it's bombproof durability compared to some of the other brands.
