This is a nice vintage Majestic Aristocrat small pocket knife made in Seki Japan. It is 2.5 inches closed and the blade is just under 2 inches long. This has a lockback lock with the lever also locking into place on the blade, so has a double lockup. To release, you must fold the lever out of the blade and then push down/back to release the lockback mechanism. A very well-made knife.
