I guess it's because they're just nothing new and there are lots of other options in the price range. Plus they're made by Benchmade, and Benchmade's resell for a decent bit less for the most part as well. The Bradley Alias, for instance, is a pretty nice knife and good alternative to a Sebenza if you can't afford one (not that it's close to on par with the Sebenza, but a good choice for half the price). However, it kind of seems a little bit overpriced. It has those lines coming down the sides of the blade like lots of Benchmades (not actual grind lines) which makes it obvious it's completely CNC'd and not hand finished at all, not even to polish off those machining lines that will actually make a zipping sound if you run your fingernail along them. That's one thing I didn't care for on the Bradley. They also have an extremely flimsy lock bar like many Ti frame lock Benchmade's. That was the kiler for me. My Alias has a good bit of lock rock and just squeezing the knife lightly will flex the lock bar up and down against the blade tang. Just a super thin, super flimsy lock bar with very little lock bar face to contact the blade tang.
Because of this, I think it's a little overpriced and definitely not worth the new price on the secondary market. For about $40 more, you can get a Pro-Tech TR3 Manual which has almost the same design but is much closer in fit and finish and robustness compared to the Sebenza. Same exact blade shape, better handle shape and just outstanding fit and finish as well as a very sturdy design and lots of nice little touches with the design. Also, you can get a Zero Tolerance 0550 for the same price as an Alias and it will be much more robust with better fit and finish and even though it's a lot more of a hard use knife, it's still almost as good of a cutter and great EDC with a much better value and better quality in my opinion. I don't know, these are just some of my thoughts.
If Benchmade would touch up the Alias' blade by grinding off those machine lines and giving it actual vertical grind lines (getting rid of the texture and at least making it look hand ground or hand finished), cut the lock bar much thicker and giving it a big, flat lock bar face like the Pro-Tech TR3 Manual, and maybe gave got rid of the blue hardware and replaced it with some polished hardware as well has upgrading all the hardware, I think it would be a much more popular knife.
