Most custom folders I have owned have been liner locks...they will not perform as well as a Sebenza. The liner lock has too many flaws. There are plenty of people who will agree with me in the superiority of the Sebenza. I have had custom William Henry knives costing upwards of 2Gs...they were awesome!, but nowhere near as solid as a Sebenza. The custom Neil Blackwood I handled was great...but heavy, a liner lock, and pricey. The Sebenza is nowhere near as neat as customs (I think it is personally, but my buddies liked my custom WH more than anything else), but it uses:
1) tighter tolerances than most customs I have handled (blade play in a Sebenza will not occur initially nor after extended usage)
2) better materials and a locking mechanism that has proven itself to be the most reliable in the business
3) the IDEAL cutlery steel for a folding knife with the best heat treat in the business
4) practical handle design and blade design which is easy to sharpen
5) practical weight
6) easy to service yourself
This is just my opinion and I could be wrong, but none-the-less its how I feel
