Hey guys, this is my first thread on here. Sorry if this was previously asked but wanted some clarification before I do anything.

Here's the story:
I got a 5/8" Thiers Issard Straight Razor from the Art of Shaving as a birthday gift a year ago. Wasn't shave ready so I sent it in to Lynn to get it honed and it was amazing. I had the Dovo 2" strop but have since thrown it away since I beat it up learning how to strop correctly and wanted to get a new 3" strop.

Now here's the big question/scenario:

I've maintained the sharpness since it was honed with the usual stropping as I got better. But, my cousin who lives with me used it one day (or tried to use it) and upon stropping and trying to shave with it I noticed it had dull points. More specifically it was sharp throughout the blade but dull in the center. That's when I found out my cousin had used it. I have since disinfected it and all that good stuff. Now what should I do? Regardless I need a new strop which I will purchase but will that do it or do I need another hone and start researching on hones, buying the hones, etc?

Again, I apologize if this was previously mentioned. Thank you in advance for any help/advice!
