I've felt this way for quite some time, and my advice is to USE them. It's hard to beat up something you pay so much for I fully understand, but at the same time you pay that much for something that is capable of being beat on. And if you still can't let yourself do that to your babies, grab two of the same knife! Some say it's silly but it allows you to punish one while taking utmost care to the other, should the day ever arise that you destroy the former. That's not silly, that's reasonable from a collectors standpoint.
Remember they can't come with you when you leave this life.
To answer your question: Benchmade Griptillian.
It's not the cheapest, but I have and I have seen it put through it's paces. If you look at the "worn, beat up and war torn" thread there's a guy there who has used his to cut aluminum fence and open paint cans. You can see in his pics that the knife has seen a lot and still works perfectly with minimal maintenance.
