NO redbone during the Tested era is the first indicator. The shield is a bad imitation of a tested era shield.

Re: Fake Case Tested XX 6380
Here are some pictures from the listing. Definitely a fake.
As stated, that bone color is from much later than the TESTED XX era. As far as I know the bomb shield was not used at Case during the TESTED XX era (it was used pre-TESTED and re-appeared in the 1990s), but if it was it never had “CASE” on it. Bomb shields with “Case” or other markings on them were introduced after early 1990s. Hard to tell from pictures but the shield appears to mounted on top of the cover instead of inletted, which would never be seen on a TESTED knife.
Interesting that the tang stamp appears to be a cold stamp, but I see no signs the tang was shaved.

Re: Fake Case Tested XX 6380
The lettering on that shield looks completely off, not like any Case I’ve ever seen.

Re: Fake Case Tested XX 6380
Since I'm sure Mumbleypeg knows Case Whittlers and forgeries better than I ever will perhaps I would be wiser to only write thank-you for transfering the pictures but I learn from being wrong. Looking at second picture it appears the edge of the master tang was straightened with a file and beaneth the top of the C it slopes downward or tapers to a tninner thickness above the choil.Mumbleypeg wrote: ↑Fri May 09, 2025 9:08 pm Here are some pictures from the listing.

Could be. I was looking for it here, but don’t see it.
Still a fake regardless.

Wow!
Probably the worst (cold) tang stamp and Bomb shield fakery I've ever seen.

Re: Fake Case Tested XX 6380
There is considerable doubt the 80 pattern was ever made in the Tested era. I don’t like the secondary clip nail mark either. I could be wrong but I’ve not seen one in that location.
Here’s a couple of legitimate knives. Note the nail nick location on the secondary clip.

Re: Fake Case Tested XX 6380
I think they did, but I have never held one in my hand. Tony Foster told me that they did. Years ago, a collector posted his example here on AAPK.
I do have a XX stamped green bone example with Tested era green bone and a Tested era shield.
If Case did make the 6380 in the Tested stamp, it was very late in the Tested era, as the 6380 never showed up in Case price lists until the late 1940's, and was first shown in Catalog #60 which was 1949 or 1950. So it was a new pattern for the WWII to post-WWII era.
The knife posted at the start of this thread is such a BAD fake, I would consider it an "across the room" fake - nothing about it looks even remotely like any knife that Case would have ever made.

Re: Fake Case Tested XX 6380
Thank-you once again for great information knifeaholic.
Regarding my previous reply, Mumbleypeg was right. I was thrown off by the reflections in the second picture.
While this fake is obvious to me know it is one more example of why I started as a collector of modern traditional slip joints and mostly remain one. It is unwise for begining collectors to start with knives that are old enough for their age to raise their value much.

Here is another equally bad one that just sold today. I don't know how to snag the WEBB photos to post here, maybe someone else knows how.

1. How do we know its a fake?
2. How does the middle backspring even work? I see it's held by the center pin but not anchored at the rear? I've never seen that.
To those who fought for it, freedom has a flavor the protected ones will never know.

That's the infamous "Alligator Jigged" bone that Case never made.

Re: Fake Case Tested XX 6380
While I'm certainly not an expert on early Case knives I think I can answer your question #2. In all the 6380 and 6383 Whittlers I've seen the middle piece is a wedge that seperates the left end of the two back springs. Each spring puts pressure on one secondary blade. Both springs put pressure on the master blade.RedRaiderRick wrote: ↑Tue May 13, 2025 7:34 am Wow someone paid that kind of money for a fake. 2 questions from a Case rookie:

During the 1990s Case made economy versions of 6347 and 6308 Whittlers that had three full length back springs similar to stockmans and whittlers Buck makes themselves and similar to post-1992 Case 6347 Stockmans. At the same time Case made more expensive Select 6347 Whittlers that had two back springs seperated by a wedge and nickel silver liners.

I think you are "right on" Slip Joint...the whole tang complex [ blade and tang] has been contrived to cover up the tang shaving.

Re: Fake Case Tested XX 6380
Isn't it kinda ironic that this same 80 model with same alligator jigging is used as an example for the 80 model whittler in our [AAPK] research page yet we are giving advice to those with counterfeit questions that defines our example a "fake"

Re: Fake Case Tested XX 6380
I too am pretty new and slim on Case knife knowledge and experience. I enjoy reading threads like these to help educate myself. I noticed on the eBay page of the whittler that sold for $700+ he had several pictures. One was a screenshot of Case jigging patterns from Shepherd Hills Cutlery’s website that showed a similar jigging pattern as the knife for sale called “imapala.” Is there a difference in that and the alligator pattern mentioned above?

How much time and skill would need to go into producing a fake like shown by the OP? It seems like a lot of work for the return. Or is the reason someone just being onery?

Re: Fake Case Tested XX 6380
Impala jigging is on new knives, usually dark colored from what I have seen. If you see that on any Case knife older than the 1990's, run away.
It could have been a repair not meant to deceive. Case never used Strawberry bone like Robeson did. Once the next guy gets a hold of it, all bets are off.

Others may be able to add more details to both of your replies.
