I have a feeling blades of this type have been discussed before, but I can't find the thread. I found this thing on Mr. Jurgen Fricker's website (see attachment below), looks like the early German forerunner of Tinker Pearce's "Tactical Death Spatula" series.
Can anybody fill me in on the use of this item or point me toward any discussion on these that may have occurred? Thank you in advance!
