Thomas,
The giveaways are all about the giving. It makes us feel good to give, and we reflect well upon ourselves by it, even if the receiver doesn't like the gift, or doesn't appreciate the gesture.
The effect goes far beyond the person receiving the knife. All the people reading can see that you are appreciating your customers in a generous way, and it generates good will toward yourself and the company.
You have chosen a unique way to do it, with sort of a "random acts of kindness" approach, which is pretty cool.
Regarding the policy of announcing only when ready for market, it has its good points and bad points. Overall, you need to protect yourselves and your IP, but there is something to be said for tantalizing your customer base with upcoming products. Perhaps there is a middle ground.
Keep up the fine work. You are leading the pack!
I am waiting patiently for a new 560 to become available in stores, and it will be the flagship of my knife collection. I am chomping at the bit for it to become available! I have a feeling that this knife series is going to be a legend in its own time.
We all appreciate what you do, and Merry Christmas and Happy Holidays to you, your family, and everyone at KAI.
