The Jamie Ike Jime Spike

We have spent nine months testing different blade styles. We have finally decided on a blade style that we that is proving to be very successful. It has a pointy end on top which is actually used to penetrate the top of the fish and moves rather easily into the brain cavity. Once there you can twist the handle and destroy the brain tissue rather quickly. For larger fish we use a mallet to hit the spike to enter the brain cavity. As with any spike, it is very sharp so use caution when using it. It's currently made of copper which I am pounding down With a hammer and anvil to flatten the end and sharpening it with a stone wheel.
