My two favorites are the custom Robert Williams that I have (I need to post some photos of it as soon as I get it back from being honed) 10/8ths, Oryx scales, Monkey tail, rounded square point and leaf and vine file work on the back. Shaved like a dream till I decided it needed a touch up and was too chicken to hone it myself for fear of damaging my lovely.

I can't remember who makes my other favorite but it is a 12/8ths monster. Black horn scales, spike. Very plain and a ton of patina but shaves like a dream and weighs a ton! Could very well be my next attempted restoration it would be nice to see the old boy in some new scales with a mirror shine!
