Gordon, that's a heck of a set of compliments and I hope you use the heck out of it.
My biggest regret is that I can't seem to get more than one of these done a quarter... but I'm working on it.
SO glad you're pleased!
(As an aside -- yes, keep it oiled, but I've been un-scientifically testing a bunch of 5160 in my damp basement and it seems to resist rust quite a bit better than some other well-regarded steels.
I think I could actually watch rust grow on 52100, for instance. That stuff needs a coating!
