Yes, I spent a good amount of time comparing the Chris Reeve Sebenza to the Bradley Alias.
In the end, I felt that the Bradley Alias was the better knife for me. The shape fits my hand better.
I've had the Bradley for about a year and a half now. I love it.
While I think CRK makes very fine knives, and the Sebenza is considered a classic, it's not my cup of tea.
Regarding the comment about the Bradley being like the Benchmade, the Bradley Alias IS made by Benchmade under contract, and is at a level between the Benchmade Blue Class and the Gold Class, so it is made to a very high standard. Benchmade handles any warrantee claims for life with this knife.
And for the question about the locking mechanism, the Bradley Alias is a titanium frame-lock.
