Beautiful knife. However, I compared it to the Erickson and Peña knives, and I prefer the other two that have a pair of symmetrical bolsters. I like how on those knives the shape of knife is informed by the shape of the spring. This knife has a softer feel. Is my aesthetic a more traditional one?
The most popular version of the "Eureka" pattern you will find is the one like the one that Kerry built, which is based upon a pattern supplied by Tony Bose. I don't know what the original knife was that Tony used for the pattern. The double-end version like Ken's built on a "Eureka" frame is something I've only seen in Levine's Guide and was based upon a depiction of an old knife by the New York Knife Co. Enrique Pena's version was based upon an old Henry Sears 3 spring whittler which he adapted to the cattle knife with two backsprings.
It would be difficult to say what's
most traditional as all are based upon the classic "Eureka" pattern but are different incarnations. All three can can be found in books like Bernard Levine's excellent guide.
I always wondered about your seemingly equal love for spear points AND clip points, Elliott.
What do you find compelling about the spearpoints?(which I personally don't care for, the blade always looks like it has a dull point, even if it is a needle in reality)

Putting aside that with custom knives you can usually ask for what you want, the "spear" master blade was traditionally associated with certain patterns, cattle patterns amongst them.
Like anything, it's an acquired taste, and there's certainly no reason to choose a spear master blade if it's not your cup of tea.
For me personally, the well executed spear blade has a certain timelessness to its appeal and when ground properly with a beautiful swedge (and perhaps a long pull), adds beauty to that sense of historic accuracy.
You will find that I generally shun redundancy in my custom knives so you will rarely see a duplication of blades within any one particular example of a pattern. I won't ordinarily opt for a spear master paired with a pen blade, by way of example. (Even if the original pattern may have been set up that way.) However, I will generally retain the spear master blade even if a clip or other blade might conceivably be substituted in its stead.
There's no right or wrong when it comes to custom knives per se, but there is a right or wrong (to varying degrees) when it comes to historical accuracy and nomenclature.
Fortunately (or unfortunately) for me I am equally attracted to patterns which feature a variety of master blades.
