Seems people often think it's for ego.
Thought I'd explain this once and for all (I doubt that will happen)
Instructors wear patches so their students will wear (buy) patches.
Patches cost a buck, sell for 5 bucks.
If you don't wear patches, they don't buy patches.
Anyone not understand that?
Same thing with MMA by the way. Seen a "tapout" shirt lately.

Happy with my Uechi crest, and my colorful gi's I buy on sale for $10.00.
