The ESEE-4 line of fixed blades boast the same flat ground powder coat 1095 carbon steel blades as the 3, but in a bit larger package. The 4's overall length is bumped up to 9 inches with a 4.5 inch blade length.
The 4's larger size pushes it into the Camp/Survival category with rounded pommels only and removable handle scales. The 4 is the perfect all-around camp tool built for slicing, skinning, batoning or starting a fire.
The ESEE-4 Category includes a 440C stainless steel option for folks looking for a more corrosion-resistant camp tool. Micarta and G10 handle scale options with available part serrated blades.
