I searched for similar threads and haven't found much, so I apologize if this has been asked and answered in another thread already.

Bradford uses optimized 3V in some models, and my question to those who own one is, how is the edge retention? And can you compare it to some production steels like S30V, so I get the idea how similar or different is it? I know that there's plenty of general info on the edge retention of plain CPM-3V, but all of it pertains to production knives heat-treated using an industry standard protocol, which is far from ideal for cutlery. Since Bradford sends out knives to Peter's for heat-treating (to ~60.5 HRC) using the protocol optimized for cutlery (designed by Nathan, as I'm sure most here are aware of), the edge retention is bound to be much different, and hence my question.

Any feedback much appreciated. :D

I'm pretty sure Nathan just made a thread explaining how he optimizes his 3V. Maybe it's relevant if Bradford uses the same protocol, go check the Carothers forum.
 
Nathan optimizes 3V using his Delta protocol, of which Peter's uses an earlier and more basic variant. Performance results of Delta are going to differ from Bradford's knives, which is why I'm curious about some personal experience with edge retention on Guardians. I'm actually asking because trying to decide between Guardian 4 in 3V and M390...
