For the Hinderer, go to his dealers and get on their mailing lists. There have been a couple of Gen 3 XM-18s that have been in the for sale section asking between $515-$550. Not too bad for the secondary market. It's really the Gen 2s that have the skyrocketed prices. I love mine

You might want to check out the Chris Reeve Umnumzaan. It won the Blade 2008 "Overall knife of the year" award. It's probably the closest thing to a Sebenza/Strider mix. Looks like a winner to me

COMMENTS: The Chris Reeve Umnumzaan is the newest model in their line-up. Popular drop point blade shape with razor sharp hollow grinds. Refined design, high performance construction are all part of this folder. Titanium pocket clip mounted for tip up carry. INCREDIBLE pivot strength and smooth opening blade. Filed worked thumb rest for increased handling. Light for it's size, due to the titanium construction. Very strong integral locking mechanism that Chris Reeve pioneered. Begin to enjoy the quality of a Chris Reeve knife.
from Chris Reeve Knives, "In every sense of the definition, Umnumzaan is a knife deserving respect. Developed from the 20+ year heritage of the Sebenza, this bold, innovative folding knife is one to be reckoned with for its inventive design features and ability to get the job done.
A ceramic ball creates the interface between the blade locking surface and the integral locking arm surface. The ball doubles to drop into a detent on the blade to ensure the blade does not open accidentally.
Typical of CRK, the pivot strength is more robust than other folders. The large pivot screw and pin are supported by large thrust washers. These perforated phosphor bronze washers reduce friction and double to retain the fluorinated grease for longer lubrication thereby extending the life of the knife.
The thumb lug doubles as the stop pin, ensuring a solid lockup. Around the lug is a polyurethane o-ring that acts as a shock absorber to cushion the impact of the lug against the handle. Never wishing to copy other designs without giving credit, Grant and Gavin Hawk originated the shock absorber concept in one of their many innovative designs. We appreciate their consent for Chris to use this adaptation of their concept."
