There's no recipe mate, it's only obtainable by killing a Tentacle in swamp.

I would suggest finding a swamp first (duh) and then looking for some Merm houses, camp out near the merm houses (not too close so you don't get your ass kicked) for a few nights, hopefully they will attack some tentacles during the night, and you can quickly pick them up in the morning - i've been doing that on my world, and apart from being killed once by hounds, I safely managed to get myself a chest full of spikes.

Hope this helped!
