The unique styling and toughness of Extrema Ratio knives is highly regarded the world over. The Harpoon II with saw back has a longer blade, tapered form and the dorsal fin making it a worthy successor of the Harpoon, a knife whose form, from the moment it came onto the market, has had international success.

This is a superb field knife which is strikingly flexible. The hollow ventral grind makes it light and manageable. Between the lower hilt and blade there is a space where the index finger can rest during precision work. The upper hilt is present only in the "F" version, where it can be used in a "sub hilt" grip in order to apply greater force when using the dorsal saw.
