Why not convex edge from the factory?

[tiguy7]

The convex grind has more meat behind the edge, so it is stronger. It is also easier to change directions when cutting because it has less of a propensity to run straight. I use a slack belt grinder (handle maker) to do convex edges. I go through about six different grits and wind up stropping the edge on the back of a running cloth belt. Since the rig is not too portable, I don't sharpen many of my knives this way. The power equipment wears out blades faster.

Someone please correct me, but won't a convex edge be less resistant to lateral forces then a V edge? So in a camp/survival/hard-use knife a V edge is more desirable because it's tougher?

It depends how it's done. You can make a V cross section and then form a convex cross section from it. It's a little weaker then but cuts better. Then you can make a V section from that convex... now it's much weaker and cuts even better. Strength and cutting for a given alloy and ht depends on the geometry. More steel is stronger, less steel cuts better. Convex is favoured because it is efficent in it's use of steel.

They both have Thier place, and it really comes to personal prefrence. All I was trying to say is v is not some cheap inferior method to be used only by heathen chop shops. I've had some very nice handmade customs before, and they cut very well with convex edges. But I also have many v grinds that cut great, and are easy to sharpen in the feild. The idea that any knife made in a mass production is worthless or to be looked down upon pisses me off.

Pretty much, yep.

I have always been able to cut what needed cutting with both types of edge. I have never had a problem maintaining a V edge, and I have never really cared if it is a perfect V-edge, so realistically, most of mine are some kind of hybrid.
