Well I will try and give you my opinion. I personally have a Sebenza, made from that "new powdered steel"
mine was made in 2003. What sets CRK apart is the quality and attention to details. They use very high end (aerospace grade) materials. They hold their tolerances to the thousandths of an inch. That's .001 !! There is an amazing investment in machines, time, and materials that must be made to get things that go flick and slice to that level of perfection. On top of that, Mr. Reeve still checks every knife that leaves the shop. I had the pleasure of meeting him at the 2013 SHOT Show, and he is a true gentleman. When you purchase a CRK Knife, you are investing in a small piece of art.
Short story about CRK: when I met Mr. Reeve, I explained that I had a Sebenza that I had bent the tip on. I admitted that it was my fault, not the fault of the knife. I had done it at work prying open a window on a call. I inquired about the cost of repairing my Sebbie. Mr. Reeve had me bring the knife to him the next day at the show. He PERSONALLY took my Sebbie, inspected it, and had me write my address and contact info down. I asked him the price and he smiled and said "we can fix it, don't worry, you only buy my knives once." Long story short, they took my knife back to Idaho, gave it a full spa treatment, fixed the blade and sent it back to me for FREE.
That is what makes them worth the cost to me.
That is MY take on CRK. You only buy quality once. As the old saying goes "buy once, cry once."
