    It took a while for me to pull the trigger on this purchase because of the price, now that I have the dagger in my hand I can say that it was well worth it. I normally collect knives but this dagger really caught my eye and I had to have it. Not only is this thing beautiful but it seems very well made. Well done Spartan Blades!!

    Perfect dagger

    Published by ANDY on Apr 3rd 2026

    The FS is a traditional standard dagger initiated around 1930s. This version is refreshed with magnacut material and modern technology design. It has an aggressive pierce point with extremely sharp 55 cutting edge. It is a symbol that US inherit the lineage and mission around the world rather than US only limitation like V42
