Question about tactical shovel(s)

Specifically the one markiplier shows off here

I want to get one for someone I know, but I looked it up and it costs about $200. I found $50 alternatives but don't know if they are cheap knock offs.

Any budget alternatives are welcome. Harpoon part is necessary

Thank you!
