What kind of hook is this? These came free with some line a long time ago and I have no idea what to do with them.

Here's a penny for size comparison. If you give me an answer, I'll profit quite a bit more from your 0.02 cents.

It is a circle hook mostly used for live bait. The turned in point sets with reeling pressure as opposed to a hook strike. The idea is to mostly hook fish in the corner of the mouth by just reeling your line in.

It's a circle octopus hook.  They're originally designed for live bait.  You simple reel into pressure, and the hook gets caught in the corner of he mouth.  You don't hook set them.  I've tried them with finesse worms and senkos, but had marginal success.  They're great for catfishing with night crawlers, though.

It looks very similar to the Gamakatsu Octopus Circle Hook Offset Point.

Looks like an octopus style circle hook to me. I know guys that drop shot with similar hooks, or fish small wacky rigged worms on them

Looks like I was too slow lol.

So this is nothing I really need in my bag. I wacky rig with EWG hooks. I use those for all my plastics.

You can use them to nose hook a fluke or drop shots or even boob tube rigs.

Jay-

Yup, what everyone else already said and i use them to nose hook 3-4" stick baits dead drifted for smallies

As said it's a circle hook, they excel with live or cut bait.  Depending on the species either just easily lift the rod and let the fish set the hook, don't set it yourself.  Most of the time fish will be hooked in the corner of the mouth, but I have gut hooked both bass and snook on a rare occasion.  A circle hook works really when when wacky rigging.  I do not recommend them for use with toothy critters, the shank is too short unless wire is used.
