How Do I Make a Gallery Wall With This?

My teenage son has a passion for flying radio controlled airplanes.  It's a fun, yet expensive sport and he's quite good at it.  He competes in various aerobatic flying competitions in the Southeast region and has accumulated quite a few plaques and trophies over the past few years.  I decided to make a "gallery wall" for him using some of his plaques and pictures from the competitions he has attended.

Should be easy, right?  Wrong!  Because of this....

These are the 'plaques" that he won while competing in New Iberia, Louisiana...part of "Cajun country".  Those are real (sugar) cane knives with vinyl letters stuck on the blade...a sharp blade.

I'm trying to figure out how to add them to the wall so that they blend in well with the other (real) plaques.  And be safe...

I've been laying out the plaques on the floor trying to come up with something.

I was thinking about hanging the knives vertically since it would be safer but then the words would be hard to read.

Do you have any ideas?  What I mean is...HELP!!!  I want to do something to the wall before he comes home from the flying "camp" that he goes to every summer.  I'm expecting him home on July 13th so think of something fast, ha!

One more thing.  I want to remind everyone that the first day of my new Google+ series will begin tomorrow.  I will be writing about how to create a Google+ page as well as giving tips on how to use it to your advantage.  The series will be four parts...one for every Saturday in July.

At the end of the series, I am teaming up with some other bloggers to bring you a large, multi-hosted Google+ Blog Hop.  The hop is scheduled for August 4th.  Please "save the date" so you can join us in a new networking experience.
