I generally won't comment on the originality of anyone's knife unless asked and or more likely asks me directly. I don't like hate mail.

I think your intentions are good, but, even the best laid plans can go astray. I want to give you some friendly food for thought.
There are some folks that don't care if a knife is original, different from most people collecting old knives that want a fine collection of original knives.
There are people that don't care so much about the history.
There are people that have different standards for obtaining an old knife and the longer most people collect, the more particular they get.
I bet you couldn't get an agreement right here in this thread of what constitutes a counterfeit knife.
To me a counterfeit knife is one that is presented as original and is not ....... or a copy catted old knife where the seller wants to make you think it is original. Deception, if you will.
In your example above, I would say it is not original, but, I wouldn't say it is counterfeited because I think everything about it is original except the blade ....... and I don't know the intent.
I would call your example a Frankenknife, a very poor attempt to replace a blade, but, I can see why they might have wanted to because if you look at the body of the knife, it's old and right handsome. I would guess the knife to previously be a fine old pruning knife. I wouldn't offer a dollar for it because I don't swap blades, but, somebody with skills to do it right might.
I have never tried to replace a blade on any of my knives, but, early on in my collecting, I sent an old knife off for a broken pen blade delete and a re-handle. I doubt I ever will again because I already have my collections near where I wanted them to be. I never intended to sell it and wouldn't sell it and never had any intent to deceive anyone .... I wanted it that way for me ..... and it turned out great. Now ....... after I kick the bucket .... if my son later decides to sell my old knives, he wouldn't know because it was a well done re-handle and he might present it as original, if somebody asked ..... but he would be going on his best judgement (because he does not collect old knives) and not be intending to deceive anyone.
I see others that looks in the catalogs and if the old knife is not in it, they get suspicious. Well ..... not all knives made the catalogs .... I can promise that. So I would say looking in catalogs proves a knife was made, but, catalogs do not prove it was not made.
Then ... you get into the territories of what is acceptable and what is not ? I know what is acceptable to me, but, what is acceptable to you or Duncan or Cal or Charlie or Lloyd or Rachel, etc.
Very likely different.
To give everybody a good example ..... say Michael has an old Cattaruagus knife laying around that is completely original and he acquired it early on in his collecting and the pen blade was broken or wore out. Years later, he runs across another of the exact same model and with a pristine pen blade, but, the bone has bad cracks or is missing ..... so he gets to thinking ..... you know I might be able to get Eric to swap those identical pen blades


.... he runs it by Eric, and he does it for him. Now he has the knife he always wanted .... (maybe couldn't find a better example) and it has a genuine Cattaraugus pen blade from the same model in it. So .... what is wrong with that ? The knife is no longer as original, but, now it is a good knife. Is that acceptable or not acceptable ? I surely would not call it counterfeited, especially if he did not describe it specifically as original at a point of sell. I would likely call it a repaired knife.
I would hate to see a counterfeited thread allowed anywhere in the traditional forums here, as it has earned a reputation for being mostly friendly and I would hate to see a rift get started. People might get really mad and leave or assign you sad emojis all the time.

I think the term counterfeited causes alarm. How about a thread that describes what to look for in non original knives, as an alternative ?


A thread that discusses, without using someone else's photos or someone else's knife, things to look for to avoid getting took. Like hammered pins and spun pins, the size of pins in the real old knives, do they match the tang stamp era, the whole look of the knife such as pocket worn bone and nearly pristine blades. Things like .. when did hammered pins start to disappear vs. spun pins, things that people with a good deal of experience still wonder about. When did pick bone start to disappear ? Which manufacturers tang stamped all blades vs. ones that just stamped the main ? Posts that address that some more modern companies re-produced some of the old knife companies knives legally and what to look for.
Things like seller does not accept returns vs. does accept returns. Does not accept sets off alarms in my head. Does accept means that if I closely look the knife over when I get it and think it is not original means I can send it back for refund, which comforts me. Feedback ...... look it over. Things you said, like the blade doesn't open right or stops at an odd angle when opened, visible bolster pins. Photos of a knife that don't show it fully opened concerns me. It might be wore out. Absence of any description of snap concerns me. ....... and so on.
I hope I didn't say anything to upset you, but, if I did .... I promise I was trying not to and that might tell you where a thread for counterfeit knives might go. For Facebook, it might or might not work out. ........... and you asked.
Now ... I'm tired of typing, thank goodness for all of you.
