Musky hunter, just one litlle question on the post you said Blood ( What kind of Blood ) I know your not talking about human blood, but what kind of blood bream,minnow, shad. I have heard of something similar to that, also holes to allow bubbles from the lure.

Sounds like a variation on a sponge hook, like the ones used for catfish. You might be able to find one of those in the right size and try that out too.

Usually cow or pig, what ever was being butchered on the farm I guess

huh thats a pretty cool idea just how do you get the blood through the small hole?

perhaps a syringe that you can get from a vet or the pipe cleaner would soak it up . It also may be corrugated blood .

Rapala has always been my favorite lure but never tried the blood trick but I will.  One of the least tried ideas is tying that loop knot--years back they included directions on how to tie it in the box.  I have fooled around with painting some red around the gill plate area and one of my favorite tricks is drilling a few small holes toward the rear to make it sit up.  This can also be done by adding lead strips to the back treble hook.  Late in the day big bass seem to like knocking them out of the water.  Good luck and good fishing.  Uncle Tom

Im not drilling holes in my ten dollar Rapala's lol they catch enough fish
