I've only seen it in photo's, but the bolster lock has a section milled out for a scale, ala Janus & Diablo, and integral bolster is split just like an integral. The text on the Elishewitz website states:
"Bolster-Lock
1/8" thick titanium liner and lock with a section of the handle milled away. A handle material is replacing the removed titanium. This combines both a bolstered knife look and a monolock construction."
It really adds to the esthetics, though. The lines of the knife flow nicely with the handle slabs on both models. I was originally going to add a Benchmade 720, then decided to move up to a small Sebenza, but after several visits to the Elishewitz website I've decided to bite the bullet, save a little longer and get something I can drool over.
There was a line in a Trevanian novel that said (roughly) "One bite doesn't taste any 5". I guess I'll use that logic with five factory knives don't provide more pleasure that one custom...
