Blade Education: Forging v. Machining, What's your thoughts ?



Blade Education:  Forging v. Machining.
A forged knife, all else being equal, will be stronger than a machined knife.
Forging means that the metal is hammered into the shape of a blade. Traditionally, a smith would manually hammer a blade upon an anvil.  Nowadays, forging can be done via a few powerful blows from large mechanical presses. 
The forging process deforms the metal’s internal grain, so that it follows the shape of the knife.  The continuous grain makes the blade stronger, similar to the way that shaping wood in the same direction as the grain makes the planks stronger. 
Machining and Stamping
On the other hand, machining a knife means that, out the metal stock, the knife is simply “shaved” into shape with a power grinder (also known as the “stock removal" method). Alternatively, the knife can be mechanically stamped out of a metal sheet, like a cookie cutter making cookies out of dough.
Grinding or cutting the shape of a knife out of the metal stock does not change the metal’sinternal grain, which remains irregular. This makes the blade weaker, similar to the way that wood planks cut against the grain are more prone to breaking.  
Factory Knives
The majority of factory knives today are machined or stamped, not forged.  It is simply cheaper to machine or stamp a knife.  Forging is more laborious, expensive and time-consuming.  Also, steel quality and heat treatment methods have sufficiently advanced such that machined knives usually have adequate strength.   
The Upshot
Get a forged blade only if you will subject the blade to regular hard use (e.g., wood axes must certainly be forged), or if you are otherwise willing to pay a premium for the extra strength and durability.  Pictured above is a forged Bowie from Scott Roush.
