I recently decided it was time to finally get a 112 , but I went browsing Ebay for a deal on a clean used one hoping to save a little over a new knife in case I didn't like it.
That's how I got my 1st 102 for cheap.
I remembered the 112 costing more than the 110 ( except the 110 isn't $36 anymore) but hadn't looked at the price in a long time, so when I saw a relatively nice & clean 1992 example for $65 I bought it. It was also coming with a nice looking aftermarket sheath that I told myself would make the knife worth it if not more.
Ultimately I payed a couple dollars more for a used knife without the original sheath and an oversized aftermarket sheath that I can't carry the knife in, so I had to order a sheath which added another $20 to the whole thing.
aside from the blade grind and slightly nicer blade finish I ended up spending nearly $25 more for a used knife thats essentially the same as you can get today.
Unless you want Diamondwood instead of ebony, had wanted ebony instead of Diamondwood 5 years ago, or want your birth year or something, I see no reason to pay what a new one costs for a used example or more for a NOS example.
Btw I love my new to me 112 and that extra $25 I have into it does not bother me, I learned a small lesson and got a good knife.
