I'm curious to hear from the people that are saying forging or stock removal have performance advantages! You guys should chime in. Honestly curious and hoping to learn, not sarcastic haha
It doesn’t really matter how a knife is made. All steels today are forged at some point and are ground at some point. Hand forging is just a method of taking forged steel from the factory and shaping it so that less grinding is needed. There are a few potential differences though. If you want forge welded damascus or sanmai knives someone has to forge weld the steels together. So you would have to buy the blanks if available or if not do it yourself especially if the combination or the dimensions you want are not available for purchase. So in this case the blank has to be created and then either forged to shape or stock removal.
With high alloy steels in general stock removal might be the only option as very few people forge these. There is Devin Thomas of course that can forge weld anything, but very few people besides him can.
A maker can ruin a steel by forging, but in some rare cases the steel can also be improved when it comes from the supplier in a bad shape as is the case with 1.2562. The improvement might be mostly from thermal cycling though, which any maker can do, and not from the physical hammering.
In the end it doesn’t matter how you get there as long as the knife is good, but some features like integral bolsters or extreme tapers might be easier to get with forging, on the other hand getting high alloy steels might be easier and more common with stock removal.
