The Franklin Mint made this knife. I posted it over in Bernard Levines forum a while back and found out that Ben Franklin probably made these back in Colonial times. (Of course, there was some debate on whether they were actually used in the Civil War, and by which side.)
I was able to acquire this knife thanks to a factory find by Tim Barker from Tennessee. I have the certificate in my safe deposit box.
Unfortunately, it seems as though that Bose fellow did not stick to the true spirit of the coffin knife when he made his pattern. I can only hope that Case chooses to rectify this with its rendition.(Cnasty, I likes yours just fine.)
I use it to de-animate frozen Cornish game hens.
