I own a Randall. Thought to be the last one built by Bo himself. I wrote to them in the early '60s and sent drawings and a description of what I wanted. I got the knife and it showed up in their catalog the next year, described as being designed by "an Alaskan professional." Well, I WAS in Alaska.
I've never been impressed enough with another custom knife to think about buying one. Not to say there are not some really great knives out there other than those built by Randall. Just that the Randall quality and fit/finish are superb. If the knife fits your hand, your use and your eye, it is the right knife for you.
Unfortunately, I don't carry it in the field anymore, since the last appraisal was $1800.00. And, that was ten years ago.
