I have received the Extrema Ratio CORVO a few weeks ago, so its now time for a brief review
The Corvo (craw) is a Chilean knife with curved blade, who was initially used by campesinos during the Independence War (1810), than as a military tool (1836, 1870). Nowadays, Corvo knives are used by some SF of the Chilean Army
There are several different versions of Corvo knife, the Extrema Ratio CORVO it originates from the corvo called aracameno.
Specs of ER CORVO are as follows:
Weight (grams): 362
Blade Length (mm): 176
Total Length (mm): 307
Blade Thickness (mm): 6,3
Blade Material: BöHLER N690 STEEL (58HRC)
Blade Finishing:
MIL-C-13924 BURNISHING
Main Grid: FLAT
Handle Material: FORPRENE
CORVO is a fairly big knife, 7 blade and 6,3mm thickness are enough for the toughest tasks. Anyway, is fairly well balanced and maneuverable, being an ER knife is as usual very well made, and the nylon sheath is one of the best on the market. On the minus side, the sheath frontal pocket is really tight, just small and very flat items (as an ER sharpener) can be stored in it.
Cheers,
