Love my key chain grappling hook! Have used the magnetic aspect several times to recover hardware dropped in awkward places. Haven't yet had a chance to use the grappling hook for anything real but have practiced in the yard a bit in case something comes along. Many of my friends have asked if I could find them one. Great addition to my EDC.
thing is ass.
magnet is hella weak (i glued a more powerful one on instead)
i thought the inside was hollow (it is but only enough to fit the 3 pins and NOTHING ELSE)
no way to store string to use with it, the the cap case it came with is too small to do so.
originally bought it to fish out keys from a wide storm drain ppl occasionally drop accidentally into on my block.
i regret buying it.
