1. Not really, I have a white collar job in California. I hardly ever need a knife and EDC might scare the sheeple.

2. No problems, I have been keeping it in my car, I'll consider keeping it in my shower to increase the humidity.

3. Not yet, but it's in the plans.

4. It works fine, very little difference.

5. I might do a set of four but I am going to wait and see how the first one polishes up.
