SOG Micron 2.0 Tanto Knives FF91-CP are some of the smallest knives in SOG's entire catalog. That's not to say they can't cut like a razor, though; these SOG knives utilize a 420 stainless steel blade crafted in the Tanto shape. Only 2.25" long, this Tanto-style straight edge knife is exceedingly sharp and only 0.075 inches thick. SOG Micron II Tanto knives feature a powerful lockback mechanism that securely holds the blade inside the stainless steel handle that you'll find on all SOG Micron knives. No sheath is necessary for this little knife, since SOG Specialty Knives has crafted it to be small enough to fit in almost any pouch, pocket, or tight space, even on your keys with the handle's keychain hole. For an incredibly small, incredibly concealable knife, purchase the SOG Micron 2.0 Lockback Knife.
