I just want to clear up my comments about sharpening.
I have a Lansky, and a Smith's sharpening set, and I hate them both. I don't like the way the edge isn't consistent across it's length, as the stone pivots, it's effective "radius" changes, and you end up with different bevel angles from tip to toe. I can see however, how using one of these on a Tanto blade would be even worse...
But having those straight edges, and treating them as four seperate edges, allows me to work them back and fourth in a straight line on the stone (a big flat waterstone.) This is far easier for me than trying to sharpen a drop-point free hand, or using a lansky style set, and getting poor results...
