Murray,
That is some beautiful collection of engraved knives you have there. A collection to be envied.
Amatori . . . well, he is a master. Some of those are not my favorite subject matter, but the quality is outstanding. Exquisite.
Regarding the guard posted above . . .
I like how the gold leaves/petals fit in very naturally with the "silver" colored leaves and petals in the rest of the engraving, instead of the gold appearing to be a completely separate element. That seems organic to me.
But there are some things about that piece that do not make sense to me. It would seem to me that the engraving border should be evenly spaced from the edge of the guard. Instead, however, the border seems to meander, so that in some places it is closer to the edge of the guard, and in other places much further away, as I have tried to illustrate by the red lines in the marked-up picture below. I would think these lines should be the same length, or at least display some kind of symmetry with respect to the shape of the guard. Instead the gap between the border and the edge of the guard just seems to randomly get thicker in some places and thinner in others - the gap seems to be maybe three times greater in some places than in others. Also, the bottom of the engraving border does not seem to aligned with the bottom of the guard. Instead they seem to be slightly offset with respect to each other (the engraving border does not appear to be at "six o'clock"). Maybe there is a good reason for all this, or it is all just an optical illusion, or maybe it is intentional and I'm just some smart enough to "get it." Just looks odd to me, that's all.
The central cutout also seems to be pretty jagged in places . . . but maybe (?) that was supposed to be cleaned up later. Not sure why one wouldn't do that before engraving, to avoid risking damaging the engraving while fixing the cutout. But I guess as long as it is fixed before the knife is completed, it doesn't matter.
