A training knife should have

[amok_nok]

here'is a post Randy did for his FB page thought you might like to read it Nok

A Training knife should have a well rounded point, If it has a sharp point it's not a training knife it's a live blade.
A training knife should have a well rounded edge. If it doesn't have a WELL rounded edge it's a dull to sharp live blade.
A training knife should have smooth contours it shouldn't have jagged edges or points and spikes sticking out of it, If it does it's not a training knife it's... a dangerous weapon. A training knife should be relatively light it's not a short length of 2x4 it's a training knife. If you stepped across from me with a tool that had a sharp point. a sharp edge. had sharp points sticking out of it. and weighed 2 pounds I'd considered myself facing someone with a deadly weapon and would shut you down accordingly. Because someone is going to get hurt with that thing and it ain't going to be me.
