I"ve been looking very hard at buying a Bradford Guardian 4 ... will mostly be used for hunting so field dressing game processing food and in a pinch maybe shaving a bit of wood to get fire tinder ... and general outdoor uses but nothing I would call "hard use" ... I have an axe and screwdrivers and prybars ... so no batoning or trying to beat it through a cinder block or repair my truck with it. #1. The knife is offered in 3 steels ... S30V - M390 - and 3V ... I know the basic differences in the steels but not much about the differences in sharpening them ... I"ve only ever sharpened the S30V ... I only have one knife in M390 a ZT but haven't had to sharpen it yet ... and I know different makers using the same steel can vary wildly ... so I'm looking for comparisions on how much more difficult is M390 and 3V to sharpen then the S30V on the Bradford Guardian knives? #2. the knife is offered in 3 grinds but I'm only interested in two ... either a Full Flat or a Saber grind ... I am familiar with both but hope to get reccomendations on how Bradfords Guardian 4s grinds are and which you feel would serve my requirements best. I know I want the Micarta handle already so wondering about the grind and blade steel ... and they offer a Nimbus finish or Stonewash ... Im not familiar with the Nimbus it looks similiar to a blackwash ....but wondered if it offered any stain or rust resistance to warrent the extra $10 over the stonewashed. Now I realise there are other knives that may be as good or better but for what I can find available currently and what I already own I think this is the knife I want to give a try. Thanks in advance for your help and opinions.
