I have the model 78 (non saw back). The edge and tip from the factory are horrible. However, 5-10 bucks at a professional sharpener to re-profile the edge and set the tip is money well spent. My 78 is now shaving sharp, add I had the edge backed up to about an 8th of an inch. It had a nice utility tip on it. Holds an edge decently, and is now very easy to re-sharpen.
It if a great knife, esp for the price. And the knife that is within it (and comes out, once you get the edge and tip issues sorted) is amazing.
