Help with meaning on tombstone

Hey all, I was just wondering if there was any reason the cross on my fathers tombstone is different than all the others nearby.

Here is an image:


I can't imagine why his cross should be different, and my mother does not know either.

It's just a curiosity thing, any ideas?

Thanks in advance.

 

That is the lutheran cross. see the link below.

I hope that helps.

 

Thanks, in all my googling that site never came up, guess my google-fu is off tonight.
