@silentheart00 I figured it out. I am adding 3 spring loaded slots that also double as an extra detail. I also added an exterior handle for the sword blade edge because I didn’t think about how they were going to separate haha. Inside the new handle I added the push button to retract the spring-loaded details that hold the blade into the handle of the hammer.

What do you think? I think that looks more believable and should hold the blade in quite nicely.
