This is a cool thread; I've enjoyed reading the responses so far.
Personally, I've had several.
The first two:
1. I was exposed to the split-back whittler, and fell in love.
2. I learned that I like a wharncliffe as a main blade, or at least a full-size secondary. Never really warmed up to it fully, even though I had a couple wharncliffes in my quiver.
These both happened when I was fortunate enough to win Gus' give-away of a Case Classic wharncliffe whittler. I carried it around for a few days, and was really "wowed" by it. It was my first split-back whittler, and has a big beefy wharncliffe main blade. I was really impressed by the construction of the knife, and the difficulty involved (as a hobby-level machinist, I know how tough it is to drill an angled hole in a flat sheet of metal.....). Also, I really grew to appreciate the wharncliffe for its pure utility, and its sleek appearance.
So, long & short of it, is that
due to the extraordinary generosity of a fellow forum member, I discovered some new favorite aspects of my favorite pastime!
(Thank you, again and again, Gus! I'm still touched by your generosity every time I hold this knife in my hand.)
The third one, is surely not least!
I'm not the kind of guy who has funds to spend on custom knives. Even higher-end production knives are often beyond my reach. I tend to orbit in the "best bang for your buck" plane, sometimes skipping into the "got a great deal on that one" sphere. So, this is something I would not have had the chance to experience, if it were not for another outstanding display of selflessness by another member, Duncan (Cambellclanman). Some time back, when Duncan gave us his good news (health-related... some of you may remember it), I sent a modest token of my well-wishes and congratulations, a little expression of "I'm with ya, buddy!" Well, a short time later, a package from NZ arrived for me, here in Philly. Inside was a gorgeous John Lloyd toothpick, dressed in amber stag with a shield in the shape of a perch! I was absolutely stunned (and still am!), and it almost brought me to tears. I now carry that toothpick almost every day, and each time I use it or handle it I think of our Kiwi buddy and his caring nature. From this experience, I have also become exposed to the work of Mr. Lloyd, and come to understand what exactly a custom knife really is. It's adjusted my perspective a bit, and now I have largely curtailed my purchasing of production knives while I put pennies aside for a future custom commission.
This is a wonderful "place" that we're fortunate to "inhabit," and is filled with some of the kindest and truest people on the planet, all crammed into one place. I feel blessed to be a part of this community.
