Ok....first off....this is personal taste...but to me, the two different color micarta spacers is a little visually distracting...they don't seem to match really well. Two of the same color, particularly the burgundy color would look better with the rest of the color scheme.
I'm not wild about the way the green spacer is shaped....how it flares out on the sides towards the edges of the guard. I'm curious if there was a reason you chose that? I would like to see the green spacer the same shape as the burgundy one and just butted up flat to the guard, letting the guard be wider than the spacer stack.
I feel like the knife would have much better flow if the green spacer was the same height on the top (spine side) as the blade spine itself so that the line of the spine carried visually through the guard and matching the spacer stack.
Comparatively, I'd like to see the same on the bottom side so that the bottom edge line of the ricasso visually carried through the guard and matched the bottom edge of the spacer stack.
As it is, the handle is not visually balanced (centered on or even) with the ricasso.
The way the bottom line of the burgundy spacer/handle rises up higher than the bottom line of the ricasso is visually off to my eye also and interrupts continuous visual flow.
Your guard shape itself seems irregular and not symmetrical side to side. When viewed from the side, the whole guard also appears like its tipped backwards towards the butt of the handle instead of being square (perpendicular) to the spine.
I'm not trying to really knock it down but most of these things are minor fixes that would really improve the visual appeal and flow of this knife, in my opinion.
The ricasso is a SUPER important and often overlooked part of the knife. It is the corner stone of a great fixed blade and dictates many other important details and design elements. It is an area that should be studied and have careful attention paid to it accordingly. I've harped on the importance of the ricasso before and even posted a thread or two on the subject.
