As reported by Uncrate,

“If an axe is going to have interchangeable heads, it’d better have a solid core — and theZai Core Axe ($TBA) doesn’t disappoint. The 28-inch helve is made from carbon fiber sandwiched in Ash wood — giving it a light weight and striking looks — while the two forged high carbon steel heads fell or split trees with the best of them and can be swapped out easily using the integrated quick release system. Whether you use it on trees or zombies is totally up to you.”
