The Best Knife Is The One You Have With You:
How many times have you found yourself needing to open a sealed package, cut a plastic tie or a protruding thread, wishing you had a blade handy? The SOG Key Knife was created to solve exactly this problem. Having the same size and thickness as a normal house key, it attaches to your keychain, literally disappearing from view. You'll always carry it with you without even noticing its negligible weight (just 20 grams).
Minimalist but Safe (Back Lock):
Don't be fooled by its small size: SOG has infused this tool with the same quality as its tactical knives. The Drop Point blade is made of sturdy 5Cr13MoV stainless steel, capable of maintaining its edge for a long time. The real revolution in such a compact design is the presence of a Lockback locking mechanism. Once opened, the blade locks rigidly in position, preventing accidental closures on your fingers during use. To close it, simply press the release lever on the back of the handle.
PAY ATTENTION TO FLIGHTS (The most common mistake!): Being identical to a normal key, the biggest risk with this knife is not losing it, but forgetting it! Remember to ABSOLUTELY detach it from your keychain before going through security checks at the airport or at the entrance to courts and events. Metal detectors and X-ray scanners will identify it, and security officers will confiscate it without mercy.
Black or Silver? The art of camouflage: If you want maximum "camouflage" in your keychain, we recommend the Silver/Brass version, as the bare metal will blend chromatically 100% with the classic Yale house keys. The Black version is perfect for those looking for a tactical look or want to match it to the car keys, which often have dark plastic shells.
It's a scalpel, not an ax: The thickness of the blade is excellent for its category, but use common sense. It is the perfect tool for unpacking M Tactical packages, cutting electrician's ties, opening letters or cutting a rope. Do not use it to pry open paint cans or to cut wood, otherwise you will compromise the pivot!
