I'm not saying this is the be all end all blade shape. I'm looking at it as a pure working knife for the everyday utility tasks we use knives for. The one thing about this blade shape is the cutting power you get because of downward leverage. My long time job which I still work part time at is a retail clerk in a major food chain. I work grocery, third shift stocking. I've used a box cutter for over 32 years cutting more cardboard then most of you will ever see in a lifetime. Not only a box cutter but I've tested knives, different makers, manufactuers, blade shapes, edge geometries and grind geometries on cardboard, plastic, plastic strapping and shrink wrap. On thing about cardboard is that it comes in different densities. The toughest boxes are the ones that hold liquid detergent. I normally make several hundred slices in cardboard every nite. The best edge holding steels I've tested are D2 and CPM154. Both hold an edge very well. But, the most important aspect of cutting ability is the edge geometry. It has to be just so or the edge will bind in cardboard. If the geometry is right on the money, the knife will still slice even when the edge feels dull to the touch.
This may or may not be the best choice for outdoor use but I think it would work quite well for most duties. I still prefer a blade with belly for game prep, especially skinning and gutting but for butchering, this shape could do well.
The shape I'm referring to is a more tapered/pointy shape like the BHK wharnie TStetz posted.
