Serpentine Jacks == Big Peanut?

That's the one! The Master Clip blade is really good (knife is excellently made too) but the Pen blade doesn't have a good tip and I can't clamp it into my DMT Aligner very well; too small:mad:

How wide is that pen blade (spine to edge)? I ask because the only clamped system I've had luck with, for small blades, is the Lansky. I haven't yet found a way to do these in the Aligner clamp either. The Lansky clamp has a 'notch' in the front end of the jaws, for smaller blades. I've used it to put new bevels on blades as small as the pen blade on a SAK (3/8" wide; I suspect that may be a bit wider than the pen in your knife). I might re-visit it with the Lansky, to see if I can do a smaller blade comparable to the width of your pen blade.
 
Whoever wrote the guide for Case patterns over at AAPK considers the peanut to e a serpentine.

I'd agree with that. As I'd mentioned earlier, I see the dogleg pattern as a more specific subset of the serpentine pattern (some vendors & makers more specifically describe them as 'serpentine dogleg' patterns). All of the serpentine patterns have that snake-like, S-curve flow to their lines; some are more subtle than others. Some serpentines are essentially equal-ended, like a stockman with bolsters of the same size & shape at both ends. The 'doglegs' all seem to have that wide-to-narrow taper from one end to the other, as well as the serpentine curves, like the Peanut and Dogleg Trapper.

Here's AAPK's description of the dogleg trapper ('40 pattern; excerpted below):

"Pattern # 40

40-52.jpg

This pattern is a 4 7/16" serpentine style jack knife that most call a dog leg trapper. They were produced and discontinued by Case prior to 1940. They have since been reintroduced. They have a clip master blade and a spey secondary blade. A few may be found with pen secondary blades.

Queen Cutlery's No.2 Jack is a kind of enlarged Peanut (only better, there said it!) Serp Frame, square bolsters, nail nicks on the same side and only 3.25" Just wish I could sharpen up that small Pen blade decently, it's so tough&awkward.

it's about 7 to 8mm.

Just checked out my Lansky setup with the pen blade of my Case 5344 SS stockman (this knife also has a little 'serpentine' curvature to it, BTW :)). It's pen blade is ~ 9/32" wide, which converts to ~ 7.1 mm. I was able to set that into the notch of the clamp, which extends the edge ~ 3/16" (4.76 mm) beyond the front edge of the clamp. I used the '20' setting on the guide to re-bevel this blade to ~ 18-19 degrees per side, based on some trig calculating.

If you're still looking for a guided setup to sharpen the pen blade in your Queen, this should work.

Thanks, I'll try it again in the Aligner. So far I've been having a bash at it freehand using a diamond rod.

Regards, Will
