Hi Andrew
Wood- The only one I can say for sure is Fisherman, they use Kumano pine (It's stated on their website) ,Hammerhead also appear to be a pine of some sort . I've got no idea what carpenter or craftbait use , (wish I knew
)
My poppers are one piece construction , I can't speak for the others but they appear to be 1 piece.
Stick baits on the other hand are about 50/50.
My lures are not available anywhere atm as they are still in development stage, the only person that has access to them is Brandon & anyone he see's fit to hand them to. when I am happy with the quality & can prove that they catch fish & still look pretty they will be made available to purchase. I hope you can understand I want to make a high quality product to give the Japanese products a nudge, please be patient. they won't be too far away.
Cheers Chris
