Jack Knife Assembly

[greentrout]

Very nice! I've never heard of a coke bottle but I like it! What dimensions is it?

It's right at 3" closed. I don't carry that one so I'm not as familiar. I'll have to pull it out and measure.

Real nice dogleg, Jack. :thumbup:

I'm more of a single-blade guy, but I do have two beloved jacks in my collection: a 2011 Case/Bose Coffin Jack and a 2015 Case Peanut.

Here's an unclothed slender little Imperial Diamond Edge jack:

For contrast, here's a much bigger, beefier Rough Rider Half-Hawk:

OK, back to work!

TedderX: The Case 6235 1/2 knife is just known as the Jack. It is one of a couple of Case patterns who are just called "Jack", though because of the size and shape the 35 is sometimes informally called a Barlow Jack.




Another one is the larger 31 Jack, which is sometimes called a Balloon Jack (I don't have one of those) and the larger still 99 Jack, sometimes called a Torpedo Jack:

Here is my 3299 1/2 Jack:


The 3299 is pretty hefty. Here it is in my hand for size comparison:


(I am 6'2" and have normal sized hands for my height.)

Here's a few of mine. A #78 American Jack. And an Imperial Peanut (wonderful gaw gift), that is as GT says, "unclothed". [emoji12] I don't know the vintage, but it's interesting that the scales, shield, jigging, and bolsters are all one piece of stamped metal. I can't tell fully, but the rivet protrusions almost look like part of the stamp also. Very interesting. When fully clothed, it was just walking around wearing nothing but body paint. Very provocative. [emoji56]

And let's not forget one of my absolute favorites, the little howling Beagle. For a guy that carries around large, heavy knives all the time, I've really taken to the Peanut sized blades.

I'm kind of surprised how few knives I have that fit the entry criteria for this thread. Lots of my knives have either a single blade or more than 2 blades. Many of my knives that DO have 2 blades have the blades at opposite ends (lots of canoes) or the blades are at the same end, but very close in size (trappers, copperheads). I have a few Barlows and Peanuts, but they have their own threads.

Here are a couple of teardrop jacks that fit this thread's description:

That's kind of how I felt too. My guess is that Trapper's and Barlow's are the two most popular Jack Knife patterns.

But the thread is a fun new twist. It really made me think about what I have. So keep them coming. I've already seen a couple knives I'd really like to try out. [emoji2][emoji16]

Here's an Autopoint from the 50s with immaculate celluloid scales, it's such a shame that some day it'll begin decomposing and there's nothing I can do about it but take lots of pics now.

Here's a picture from the other day. Jack's are my favorite! I really like them in the 3" size. My current carries are the Kabar 1026 and Case 62024 1/2.

Those little Kabar Jacks are gems, ecallahan. Both with and without endcaps.



A good old Imperial


fancy little Gunstock



And of course my favorites: the Bareheaded Ebony Jacks.

An excellent example of a Congress Jack.

To avoid confusion to our newer members, I think it's worth noting that that Jack Knives can have a different form, either with a single blade, with two full-size blades, or with blades pivoting from both ends :thumbup: The classic Jack Knife described, however, is probably my favourite pattern

Maybe I could use some education here. I thought a jack knife by definition was one "full size" blade and one smaller blade, on the same end. Seems you think differently. What is the definition? And if it is different than what I think, what is the proper name of what I consider to be a jack knife?
