Before I start the post; some backstory.
A few years ago I went to a anime convention cosplaying a horror character and this weekend I’m going to another cosplaying the same character. I lost the tin foil knife I used though so I worked on building a Lego prop knife; this is what that idea turned into.
I’m not really sure about the moc backstory he’s just a transforming knife like transformers arms microns.
I had a few versions before but they were all too bulky for a blade.
