Tyrade83, thanks for the interest! No variants there, but yep, they are different - home mods by yours truly.
Top is in fact an ASH-1, of course. Skinny. Started out coated. I stripped her, polished the edges, "melted down" the choil, slow ground a thumb rest, took the grips way down and countered for me, and just a week or two ago finally gave her a comp'ish finish up to 1000 grit and stoned her to a razor's edge.
Bottom is a SOB Prototype that I wanted to pair with it. I absolutely hated the brick grip texture and it had too much belly in the handle for my hands, so I took the slabs down a good bit, reduced the grip belly, and contered 'em like the ASH, slow ground in an ASH-like choil and bird-beaked the pommel to match best I could since I could not get two talons in there, and gave her a matching thumb ramp. Polished the edges and melted the choil like the ASH.
They make a great field pair for me!
This is my skinny ASH that I gave some original SH touches to. Stripped, satined, made black linen scales for mounted with stainless corby bolts. One of my favorite knives to use.
