The ESEE-4 is one of the most popular ESEE knives ever made. With its 3/16″ thickness, it’s the perfect blend between toughness and cutting efficiency all in a small package. If you can only choose one, then the ESEE-4 is the do-all workhorse of the ESEE line.
Our stainless steel knives are made from 440C. It should be noted that stainless steel is not as flexible as carbon steels. Any excessive flexing of the blade may cause breakage.
ESEE knives are made in the USA with absolute attention to quality materials and care during the manufacturing process. We stand behind our knives with a 100% lifetime, unconditional guarantee. If your ESEE knife should ever fail we will repair or replace it. This warranty follows the knife throughout its life, anywhere in the world. View the warranty page.
ESEE knives made from high carbon 1095 steel will rust and stain if not properly cared for, especially on the cutting edge and around the laser engraving. It is the user’s responsibility to keep the blades properly lubricated and cleaned. We suggest using a dry film rust inhibitor on the blade. Use Lock Tite when assembling any hardware, such as attaching the clip plate to the sheath.
