Well my favourite is my 18 5.5 in O1, its the first Randall I ever saw, in a book as a kid, never thought I would ever get to own one because I live in New Zealand and I figured that by the time I ever manage to get the money together to travel to Florida USA to buy a knife Bo Randall would be long dead and buried and the Randall would be a thing of history, well that longing never went away and Lo and behold because the Internet and The Randall family tradition I eventually managed to get my very own 18 (thanks Capt).
Second would be my little 10-3, damn handy little thing, love it to death.
My third is yet to be decided, I do rather fancy a Sasquatch, or a little 26...27 is kind of funky, the 28 looks very practical...it's the fun of trying to decide that keeps me coming back and drooling over the pictures you guys post!
