Sounds like a Camillus contract model from the 60s or 70s, if it was that hard.<br><br>A Ka-Bar "k-bar" uses 1095 (IIRC) carbon, which makes it easy to sharpen, and is a little denser than the high-chromium crud that Camillus uses. Cam's are a little better these days, but not enough for me to use them as anything other than throwing knives.
