If Klingons were forced to act more refined at the table, I think that they would have no problem using Jeff Pinard's cutlery concept. Although they may not be as deadly as their traditional bat'leth weapon, these pieces certainly fit into the general deadly mold.
Bold and modern despite the obvious archaic feel to them, Jeff Pinard's cutlery concept is unlike anything I have seen in this department. Inspired by the Japanese katana rather than any Klingon blade, the knives and forks that mimics this sword are sleek.
I especially like the asymmetrical lines of Jeff Pinard's cutlery concept as well as the different materials used, specifically the dark wood. Jeff Pinard's utensils would be perfect for a steak meal.
