Yes buy that custom and carry it. It will be hard to put them first few scratches on it, but it would make a great EDC.
I carry all my higher end blades, as do most people here. There is something about "using" a custom blade that just feels right. They were made to be used, most any maker will tell you that. Also when you get up in the $450 and up range most knives can be refinished. Most makers are very proud to see there knives in use, and will tune them/refinish them if asked. There might be a fee, usually not over $50.
I see my "keepers" as knives I will have, and use till I die. So I do not want to have them refinished, why would I want to erase all the time I used them? (I'm sure my kids would rather have dad's old scratched up knives that got carried, than dads brand new looking knives that never seen any use.

)
I have also found that, when you have a knife you have really been wanting, and finally get it. Its like your "want" for new knives disappears. As you have what you really been wanting to have. Its not a substitute, so your not really looking to fill any void. Hard to type what I am try'in to say. Just get it and post us pictures................................
If its not what you wanted, I'm sure you could sell her here for roughly the same price you paid. Thats another plus with higher end knives.
You could get that Crawford use it for a three years everyday, then sell it for 20% less than you paid. Try that with a Gerber Paraframe!
BUT.............if you can't carry it, I'm not sure if it would be "worth it." Thats totaly up to you. I would not spend that dough on a knife I can't carry. All my knives, see pocket time or they get purged.
Why would you not be able to carry it? Is it blade lenght?
