Since I get to play with a lot of knives, I give you my two cents worth.
For a great factory knife, try the Tops version of the Armageddon designed by Trace Rinaldi. I love it!
If you can go custom, I'll agree with the post above. Jerry Hossom or the Jones brothers can make you a happy camper.
Any of these three will result in a knife you can keep for a life time and they all are worth every penny. Anytime I can get a knife and a few years later I can still say "I'm glasd I bought it!", I think the knife is worth suggesting to others.
