Blade style：SPEAR-SPINT
Known for their symmetrical shape and robust point designed for penetrating thrusts, these spearheads are traditionally double-edged, but these knives are more accurately described as daggers.
Blade steel：CPM-S9OV PREMIUM STAINLESS STEEL (59-61 HRC)
S90V is a true super steel, offering significantly improved corrosion resistance and higher wear resistance than any other steel in our range compared to 440C.
HANDLING：6061-T6 ALUMINUM WITH CARBON FIBER INSERTS
Exceptionally robust yet lightweight. Aluminum can be anodized in many colors and milled with fine details. Furthermore, it is naturally corrosion-resistant.
OPENING ACT：AUTOMATICALLY
"Autos" have a button or other operating switch that mechanically opens the blade without the user having to operate the blade.
