I'm glad you brought this up. If you look at knives in the different price ranges you will notice that the materials used in the knives about top out at 100-200. titanium, carbon fiber, g10 etc. for handles and anything from 154 cm, s30v, s90v, etc. steels can all be found in that price range. You will also find these knives to be of very high quality and f&f, no blade play, solid lock up, etc. The lower the price the less expensive materials used and possibly less of a quality f&f. That's not to say it's any less of a cutter but the increase in price is because of something substantial, the materials and craftsmanship.
When you look at a more expensive knife, in this case the sebenza you see a much higher price then the 100-200 range but yet the materials are basically the same. The blade play, ff, lockup will also be very good. That is where I don't understand. The materials aren't any better. The blade play, ff, lockup, tolerances are already so good on the 1-200 knives does the .0005 really mean anything? Will it even be noticeable? If it is does that justify a $200 price increase? I'm not so sure that it is and I can't imagine something being any tighter then a top of the line BM or Spyderco.
I understand that some people may love the look, design of the knife, the ff, materials and quality and I don't have a problem how someone else spends their money. If they like it enough to buy it that's all that matters.
