I have the complete plaque, so I tested it out for you. Here's what I learned:
-The flip side of the blade isn't painted so you'd need to do that.
-There are two pegs and holes; one for the blade and one for the handle
-The one on the blade goes through the whole blade and the flip side of it does fit in the peg on the, so you can do that.
-However, when it comes to the handle, there's modification to be done. The handle only has one peg hole on one side. I doesn't go all the way through. So, you would need to first drill a hole one the flip side so it has a hole to put in the peg. Next, you would need to fill in the existing hole of the handle with apoxie or something.
So, it's possible, but will take some work. You need to paint part of the blade, drill a hole on the handle, and fill in the hole that's already in the handle and you can get away with it.
