This little Queen knife

At first I thought this was a 1/2 whittler but I think its a swell center double end Jack? What is it? picked at a Amish owned swap shop for 15 bucks. Most sure its delrin. Pretty decent shape for a 60-63 model. bit of blade rub & very small crack at a pin.

robpa,
It appears your knife is a #47 Ballon Pattern. I found it in the 1959 Queen Catalog. I can't make out the stamp in your picture but the 1961 through 1971 Queen's had no tang stamp. Your stamp might fit in the '58-'60 era or earlier, just hard to see.
Most of the time Delrin imitation Winterbottom is easy to spot. I ain't sure about yours. Personally, I haven't seen a lot of Delrin handles on Queens with cracks, more of the real Winterbottom handles will show cracks on used knives. (This is just my observation about Queen. I have several brand name knives N-I-B that have cracks in their Delrin handles.)
I like any old Queen!

Half whittler is a term used by Case, maybe 1980s or newer. No such terminology used by other companies or Case back in the day. Technically a double end jack has two backsprings so if your knife has only one backspring it is a large pen knife.

I agree, like many other names “whittler” is a term invented by collectors, probably in the 1970s. In the cutlery company catalogs of that day those were pen knives, with the other adjectives depending on the shape of the frame. Such as balloon, or swell center, etc.

So I’d call that a swell center pen, or balloon pen.

been working on this. It is a #47 1/2 whittler(2 springs) as per the Queen reference library., made from 1960-1963 and sure appears to be Delrin(Queen began using delrin in 1959. I just need to organize my paperork so I can better reference the stuff. Thanks for the input.

Whenever I see the term "half whittler" it makes me think of a knife that is built on a common whittler frame with just one blade in the small end. The thing that makes it a half whittler for me is that the small blade, unlike a normal pen knife, has a "catch bit" that is used to make up the difference in thickness between the pen and master blades, the master being thicker just like in a normal whittler. In a normal pen knife the master and secondary are the same thickness and therefore no catch bit is required. JMO
