Double-Ended Jack vs. Half Stockman vs. (my brain):

[meako]

Charlie -you are forgiven and no apology required.
I now see that you were coming from the cellar of snickering- surprised I didn't see you as I pretty much live there.
Incidentally I did email Fausto with all those scans.
I tried to post them in a more recent thread for which I got modded due to the copyright question as well.
cheers.

I don't know how I missed this first time around. Fascinating, engaging, insightful, teasing, cheeky and downright hilarious at times, this read has made my morning.

Good job all contributors.

This far down the road, "My brain" remains the clear loser, but it's delightful to see this thread resurface. Thanks, Deskil!

Now, back to another current pattern ramble, in which I am wondering anew if there is such a thing as a sleeveboard jack (blades pivoting from smaller end of the frame), or if that's a misnomer.

(Also wondering who gets to Say, given how much we inadvertently rely on others' imaginative nomenclature as made up by them in various yesterdays. )

Confusion fodder:

Serpentine Jack (2 springs, 2 blades) 2 13/16" frame
Coffin Jack (2 springs, 2 blades) 3 1/2" frame
Barlow Jack (2 springs, 2 blades) 3 5/16" frame
Barlow Jack (1 spring, 1 blade) 3 5/16" frame
Congress Pen (1 spring, 2 blades) 3 1/8" frame
Congress Whittler (1 spring, 2 blades) 3 3/4" frame

What’s in a name? that which we call a rose
By any other name would smell as sweet;

In order of appearance:
>why do I like the S-K-discovered name "Jumbo Pen" so much??
It does apply nicely to Deskil's 6247 PEN, one of which I also have somewhere(???)!

Thanks Meako!
signed, Meeko!

New post coming after dinner!

A resounding YES to your question!
If I may quote a noted authority, BRL, please read this.

I disagree with the "blushing" label above, Jon. IMO, you can call it a Double-end Congress Jack, or colloquially, a 2-blade Congress, but it is not a whittler.
To be a whittler as defined by Whittler collectors it needs the proper configuration, to wit, paired, split, tapered/paired or tapered split backsprings.
It sure smells sweet though!!

I disagree with the "blushing" label above, Jon.

I disagree with myself too Charlie. Thanks for paying attention .
I agree a 2-blade Congress is a useful descriptor for both the small and larger one I pictured. Im also inclined to call them a single spring congress..., avoiding the word "half". I was also avoiding calling it a Half-Whit, a remark I sometimes resemble..(out of respect for your comments against the "half" term, I did read this whole thread before posting).

Here is GEC's version of a Half-Whit.. I think the name is somehow appropriate, though histerically incorrect (typo pun intended). I would call it a Wharncliffe Dogleg. Since its handle is 3.5", it might be what Ken calls a Pen, or a double ended Jack... confusion abounds

fwiw, I was just looking at this catalog from 1946 http://www.collectors-of-camillus.us/Catalogs/1946-Camilluss.pdf and notice the term Texas Jack for a knife that has blades at both ends, as Ken points out here:

A double ended jack can be built on different frames, but what distinguishes it from a pen knife(which commonly have a blade hinging from both ends) is the length, generally over 3 1/2 inches.

There is also a Congress Pen listed.

I also agree with your split spring definition of a Wharncliffe Whittler. fwiw, here is another use of the term whittler:

And to add to the congress whittler confusion, here is one being called a
"dogleg swayback whittler" (not my knife)

Is that a correct naming for what appears to be a small 3 blade congress?
