my ultimate knife:

a 20" long x 2" high blade, 26" long overall, shaped like the DogFather, and with Res-c handle. 1/4" thick blade, convexed and razor sharp. Tip shaped like the BRKT Golok. INFI steel. It would easy to sharpen with a ceramic stone and would hold an edge thru the worst abuse. Tan coated with tan Res handle. Sheath would be kydex with shoulder rig, with another sheath for a SOD on the opposite side. There would be a smaller ultra thin knife on the big sheath, for general use, making ultrathin shavings etc.
