Queen makes a nice barlow.
The Waynorth (Charlie Capagna) special orders are quite nice but sell out pretty quickly (usually about 3 1/2" closed length and the traditional barlow size.). If you like small ones, the Waynorth Lick Creek Barlow (about 3.1" closed length) is kind of nice. I just bought a two blade Lick Creek Barlow a few days ago. These were made by Great Eastern Cutlery (GEC) and you can always depend on a quality built traditional knife.
