Yeah, that pretty much puts to shame my deer antler runes, my silver ankh, my driftwood walking sticks that I take soooo much time soaking in oils, sanding, bringing out the reds and bowns and whites of the wood. All of those kinda just stand on the sideline and hiss cattily.
From one artisan to another, I have to say that this is masterful work. The choice in finishing and materials really takes it over the edge. It is beautiful beyond belief, but it appears a bit plain. Lemme'splain:
Sans the sheath, it appears neolithic (expert neolithic) but the grip wrapping takes it a few thousand years into the future, where a design, or weave, or something (I am not sure exactly what) would make it more personalized and decorative, while still being functional. As far as battle/hunting functionality goes the sharp corners on the handle would hook on objects, so those would need to be rounded, but I am certainly not saying to change this graceful piece.
If I were to make any real suggestions, and it pains me to change such a work of art, I would (on the next go around) remove the sharp catches (corners) that keep the huntr/warrior from quickly and easily twirling the knife mid-ight from stabbing to punching grip (pointy-end facing the other guy to pointy-end facing back, blunt edge tight against the foremarm). I would get with our expert jeweler who made the na'vi necklace and see what she thinks about a pattern grip wrap for the interior hilt (between the pommel and the blade) and even grove the handle to give the wrap extra staying power rather than simply relying on a high-tension wrap.
Maybe a restraining cord (please forgive me for forgetting the correct term) in the pommel hole (a leather wrist strap to prevent losing one's knife if it is pried from your hands). This is of course ancillary. The thing as it is, is a beauty, and the colors are spectacular, from the sheath to the blade.
Oh yeah, and then the final owner would have to blood it (slice themselves and bond with the blade) to seal the connection between them. "Only once, and by mine own hand and volition."
Okay, so there are my thoughts.
