Honestly I think a lot of ~$100 knives are expensive, BUT to me a Sebenza is "worth it" because there really is nothing quite like it. The Strider Folders are "worth it," again, because there really is nothing made the same. I've had several Benchmades and Spydercos & a couple Kerskaws that just leave something to be desired. As long as mid tech companies like Chris Reeve Knives are around I'll have no problem paying 3x the cost for, IMO, 3x the quality/design.
I would love to try a Hinderer, but I DEFINITELY draw the line at a knife that costs 2x the price of a Sebenza/ SnG. I'm VERY happy with the latter two & it's just not possible that the Hinderer is actually 2x the knife.
