Many who bought test team blades are keeping them in safes an won't test them one bit. It's a knife you paid for, don't worry too much about your responsibility.
If you decide you don't like the knife, you can sell it after your sox months are up, but don't give it up just because you aren't using it enough. To fulfill some "duty"
The test team is a neat marketing idea and I hope they implement some changes suggested by test team members, but this is a product you purchased, not a gift.
All IMHO of course.
