Shipping 8-10 days
This folding knife is projected for those who are looking for sturdiness and reliability of a fixed blade but also for compact sizes. Its N690 steel blade is available with Drop or Tanto point. For standard use the well known liner lock is enough safe. In case of hard extreme works it is requested to insert the steel pin in the proper hole to cross the handle and the blade, obtaining in this way a sturdy and reliable knife as much as a fixed blade. The steel clip can be removed or even placed on the opposite site of the handle by replacing it with the second supplied clip. It comes in four different versions: HF1 D BLACK, HF1 D DESERT WARFARE, HF1 T BLACK, HF1 T DESERT WARFARE.

extrema ratio arditi black
(ref.: 04.1000.0220/BLK)
Shipping 8-10 days
A particular situation created in the early years of the first world war found soldiers in increasingly more complex confined situations. These situations demanded the formation of units who over time had to excel in hand to hand combat. Our assault units the “Arditi” had their own knife. They made these knives by cutting off the tips of their long bladed “Vetterli” bayonets of 1870 which in the past had been problematic due to its long and unwieldly length.

Today on the occasion of its centenary, we remember this important piece of Italian military history with a celebratory version of 1,918 pieces only. This version comes with black blade and a black cordura sheath.

Should you like further history and background to this unique knife you may find more in the book "Storia dell'arma bianca italiana" by Cesare Calamandrei ISBN 978-88-253-0199-1
