There are more than is in this pic but this covers the basics I think. The Chisel grind, and the tanto are not here but they are both newer additions I think to the massses since this was printed.
Sorry for the double of above. I don't know how I did that but nevertheless here is some more from a paste of an old thread.
Flat V grind=good choice for skinning, and carving. slicing ability above average with only fair resistance to abuse.
Modified V= General purpose grind. Also called the Saber grind or Scandi grind. Probably the best GP grind actually. Good slicing ability usually but not as good as a flat, higher resistance to abuse than flat.
Hollow grind=Outstanding slicing ability usually. Weaker usually because it is ground thinner so it can have a low resistance to abuses. Used to pry or when hitting a bone can nick or break the edge and/or past the secondary bevel.
Concave grind=Very similar to hollow grind only full concave on the blade. Abuse resistance is usually poor but slicing is high.
Convex= High resistance to abuse. Long edge life usually. Seen primarily in large choppers, machetes, axes, cane knives. Traditional sharpening of these was done with a file or course stone. Slicing ability on the bigger tools is quite poor.
Tanto= Sabre or Mod V grind with reinforced point for higher resistance to stabbing and prying due to increased thickness.
Chisel grind=One side of the blade or cutting tool only. Such as wood chisels. Usually strong, and easy to sharpen. Most often used in general utility tools.
Modified V w/fuller= High saber grind with fullers or blood grooves as they were called and made famous in WWII. Also seen in flat grinds on occassion. The real purpose is believed to be weight reduction in bigger knives and swords. Pretty much the same in all categories as the Mod V grind but perhaps less able to widstand abuses although this is argueable.
