Step 8: Blade Shape
1 Clip Point: The clip point blade has a fine tip, so is good for digging and picking. You can also sharpen the curved section above it, to make a lethal hunting weapon.
2. Spear point: A spear point or drop point is the standard blade shape used in penknives. it has a fair amount of material, so is very durable, and is good for cutting. It is not quite so good for delicate tip work, but is still a very useful blade shape.
I can't tell you which one is best, it all depends on what you intend to do with the knife. You would use all of the below shapes for different purposes, so think about what you are likely to be doing, and make an educated choice. Personally, I would choose a Clip point, because I do quite a lot of delicate work, but it is up to you.
If you are likely to be doing much skinning or gutting, then you might want to consider a serrated or wavy blade, which cuts through flesh like butter, but is harder to sharpen in the field.
