Sal, since you asked, IMHO, with all do respect, whatever you design, please, NO finger choil.
And if possible, make the blade start from the handle, or as close as possible. Think Bill Moran without the "choil".
just my humble opinion. when whittling or working with wood etc, I personally find the hand position awkward if there is a choil. Say Perrin Street bowie or Street Beat, love them both, but they don't "feel" right (for me) for such kind of edc use.
Think about a puukko. Perfect as it is, no need for a choil. You can use full 5 finger force of your grip if needed when using the knife, without the forefinger being in an weird position. Once again, thats just me, because I'm familiar with that kind of grip.
I don't own any Mules, always seem to miss out on the interesting (steelwise) ones, but i'd buy a longer blade mule with a "standard" steel anyday. Waiting for the Bow river like crazy.
A scaled down Temperance 2? the handle looks perfect.
