====Advantages of open-die forging====
* Reduced chance of voids
* Better fatigue resistance
* Improved microstructure
* Continuous grain flow
* Finer grain size
* Greater strength<ref>{{cite web|title=Forged Crankshaft Advantages|url=http://www.glforge.com/crankshafts.html|publisher=Great Lakes Forge|access-date=28 February 2014}}</ref>
* Better response to thermal treatment<ref>{{Cite web|title=Advantages of Forging|url=https://www.frisa.com/files/downloads/advantages-of-forging.pdf|website=Frisa|access-date=2020-08-31|archive-date=2021-04-17|archive-url=https://web.archive.org/web/20210417141555/https://www.frisa.com/files/downloads/advantages-of-forging.pdf|url-status=dead}}</ref>
* Improvement of internal quality
* Greater reliability of mechanical properties, ductility and impact resistance
"{{visible anchor|Cogging}}" is the successive deformation of a bar along its length using an open-die drop forge. It is commonly used to work a piece of raw material to the proper thickness. Once the proper thickness is achieved the proper width is achieved via "edging".<ref>{{Citation|title=Cast steel: Forging |url=http://steel.keytometals.com/Articles/Art168.htm |access-date=3 March 2010 |archive-url=https://web.archive.org/web/20090218161236/http://steel.keytometals.com/Articles/Art168.htm |archive-date=18 February 2009 |url-status=dead }}</ref> "{{visible anchor|Edging}}" is the process of concentrating material using a concave shaped open-die. The process is called "edging" because it is usually carried out on the ends of the workpiece. "{{visible anchor|Fullering}}" is a similar process that thins out sections of the forging using a convex shaped die. These processes prepare the workpieces for further forging processes.<ref>{{Citation|last=Kaushish|first=J.
