Already posted this in another thread (Too Nice to EDC), but most applies here as well:
--------------
I would recommend getting a smaller knife like Boker Subcom or better yet Gerber EAB and carry it in addition to your expensive knife that you so afraid to carry and use. This will let you have your bigger (or not so much bigger) most favorite knife with you. You get all the comfort, looks, features of your pride and joy when showing it off, and using it for light every day tasks (cutting soft material and such). Your favorite knife will stay pristine for a very very very long time. And if you need to perform a task that most likely will scratch or damage your knife, just use Gerber EAB (or whatever).
I carry my Strider PT most of all, and I'm not afraid to use it, but I like to carry EAB or Subcom just in case. Like when I needed to cut a whole bunch of wire mesh material on a screen doors. I could use Strider, I would care less if I put more scratches on it, but I knew that task will dull the blade pretty bad, so I just used Gerber EAB, and replaced the blade later on. No sharpening, no problems. If you carry Boker Wharcom you can actually open cans with it (not comfortable, but doable) and your Sebenza (Benchmade, Spyderco, Whatever) will stay safe. Anyways, most likely 95% of your everyday tasks will be a light use (unless you have some special job) and you can carry and use your baby without feeling bad about it.
Also, if you tend to carry big knives, having sub-2" folder on you will help to avoid scaring people in some situations.
If someone will ask to borrow a knife for a second, give them this small inexpensive knife (or don't give anything at all) and don't worry about it.

Too add to the adove:
On rare occasions, if there is a somewhat dirty task to do and I can't clean up the blade right away, I'd rather do it with Gerber EAB (Or Subcom) and keep my main blade clean for food and other tasks.
