Tool Logic SL7 Combo Knife packages all the options from the SL Series of folding knives into one comprehensive knife for survival and utility. This Tool Logic knife utilizes all the key components of the Tool Logic SL Series to create a highly useful knife that keeps itself sharp, sets fires, and lights up your path. All these components are built around a 3" long, incredibly sharp partially serrated blade with an oversized thumb notch for easy opening. Tool Logic SL7 Combo knives includes three accessory attachments, each of which can be slipped into and out of the accessory slot at any time. Tool Logic has packaged a magnesium alloy fire starter (to be used in conjunction with the blade), a diamond blade sharpener, and a magnetic LED flashlight as accessory options for the SL7 Combo, all of which can be found on other SL Series knives. The flashlight is particularly useful; it's the same one used on the Tool Logic SL1 Knife, with a rotating magnetic base that will stick to any metallic surface for hands-free lighting. All of these components are built around a durable steel frame, meaning the SL7 will last for a long time to come. For a comprehensive survival knife with versatility at its core, purchase the Tool Logic SL7 Combo Survival Knife.
