I know the feeling, I had a whole set of professional chef knifes stolen by some wankers I had to work with, after my aprenticeship.
Genuine Ka-Bars are really expensive now. I bought a new USMC Anniversery Edition whatever thingy a few years ago, for $150 or so. Original WW2 in good condition can cost even more.
Or you can get one from China for $15... :)
