Hi Phil
Thanks for the additional info on the 3G steel used in the Jarl. I have one VG-10 knife and it has been my experience that it is an excellent steel for knives,but I have noticed that the blade on my Fred Perrin Street Beat from Syderco has a tendency to chip...I don't know whether that is typical of VG-10 or unique to my knife perhaps the heat treatment was off. I wish I had more VG-10 knives so I could comment more extensively. I believe I also heard Virtuevoice of YouTube fame say that he too found VG-10 chippy. I don't know anything about other super steels although I will shortly have a folder made of REX 121 super steel with a hardness of 70...the the custom folder will be made by Farid. BBTW way, you might want to check out Fallknivens Cobalt steel which I think falls into the super steel category. It looks interesting, but I am curtailing my knife buying so I won't tempt myself...at least not yet!
Go for the Jarl my friend...it has it all, beauty, strength, edge retention and flexibility. It does have hefty price doesn't it, but I have no regrets, although I could have done without the donngle sheath.
