i guess you all are more hard core than me when it comes to knives. i wouldn't look for an out of production pattern. im not a knife collector.
I don't think it's so much an issue of hard core, we're talkin' users here right? If I were trying to fill out a collection of Case Trappers and I was missing a 1920s certain and they were better impossible to find than I might settle to fill the hole until a better more pristine one came into my hands.
I use almost all my knives at one time or another, whether they're 2 years old or over a 100 years old so when I buy/aquire a used knives I evaluate it and what my plans are for it. Some just need a touch up on the edge, others might have a slight wrinkle, (nothing I usually can't fix) while others become parts for other knives that are repairable.
And yes I'll admit some I will pick up just because it was an unusual pattern or something I haven't seen before, (yes my name is Ted and I have a problem, I accumulate knives) so I find a use for all the old knives I get.
To the op, I'm curious about a few things here:
1) Do you collect/buy traditional patterns exclusively and if so is it just 1 or 2 knives you own? In that case I can see your point but you will miss out on a lot of old unusual patterns, some that haven't been made in in over 50 years and aren't likely to be made any time soon.
B) What are your reasons for not buying used? If you've read the thread you started you'll find a hundred reasons why people here will buy used but I'm curious as to your reasons for not. Certainly it can't be an issue of quality, there are definitely used examples out there that are on post with a new knife, sometimes even better on the average.
Is it a gross out thing, kinda like using someone else's toothbrush? That I kinda get to, I'll replace the tooth pics on a used SAK when I buy one.
Finally and I'm not trying to start anything but you started an interesting thread here as you can tell by the views and replies, yet your responses have been very limited, have we answered your question already?
Inquiring minds wanna know, well at least I'm curious.
