Good idea for a Thread. I've actually had a few great experiences that might qualify.
One of my early really great ones was finding a batch of new Red-Alox Harvesters... a few were sold here and on SOSAK. At that time I had a hard time getting $55 for them... I think the last one went for 75 to collector. Don't know why so many prefer the Farmer.
A very recent one is partially documented
in this thread. Which is part of a bigger story.
A sader story is I was estatic when I got a '64 Red soldier for a great price... but was very sad when it got lost in the mail and never arrived. I'm hoping one day it will just appear in my mail box.
I've been able to get quite a few great knives, and I just like investigating them.
At one time I thought I would never find an Alox Technician... then I had one day I got one... man love that driver.... then one day I found I had a handful.
Life is Good! SAKs are Awesome!
