Len, Not my specialty, for sure it's a very interesting personalized variation and Thanks for Sharing. Yours looking like it most likely is in an S. 84/98 service bayonet frog is it marked on the back? Fairly recently elsewhere, there was a lengthy and IMO informative discussion regarding the Ch.A.W. version. Still being investigated, some of the things that were looked at appear to call into question the ID as a Luftwaffe Forestry Dagger. No period evidence found pointing in that direction. None. Of course it's always possible that somebody has some actual verifiable period evidence that could be brought forward - but that does not so far seem to be the case. Best Regards, Fred
