I have a very large collection of military/survival type knives and bayonets I’ve collected over 30 years. To me this embodies some of the qualities of many: nail puller/wire cutter slot for sheath like an M-9?, top/bottom short saw/serrations (pretty damn short if you ask me), top saw blade, handle pommel end stop like an issue Ontario Knife machete, etc.
Personally, for me unless this was able to bite through steel rebar with blows from a three pound short handle hammer, I don’t see where I’d spend $300 for it. I’ll be honest, I’m not a survivalist or an expert knife fighter so my opinion probably ain’t worth duck squeeze, but there it is anyway.
The clue for me was visiting the site where the article explains its features, etc. One would think that the writer would want to get the namesake’s correct spelling everywhere (e.g., the picture of the M. Parry (spelled Perry).
