I just got my large Okapi 907E lockback yesterday. After having only good luck with the Okapi 1979/3 slipjoint, I decided to go whole hog! It was easy to sharpen & locks up like Fort Knox! The steel is like they used in the old carbon slippies in my opinion. Not the greatest in the world but, not shabby either. It is 5.5 inches closed with a 3.75 inch blade. Really pocketable & light for such a large knife.:thumbup:
