The Benchmade 3550 Mel Pardue Automatic Knife Satin Plain Edge. The 3550 Pardue is another great automatic knife from Benchmade. The small size makes it convenient to carry and the black coated pocket clip is a nice touch. The 154-CM spearpoint blade shape of this small auto offers enhanced tip qualities. Push-button automatic blade action snaps out fast. The black anodized 6061 T-6 machined aluminum handles are comfortable and thin. The sliding safety works without a hitch. Overall, the 3350 is a great choice for everyday carry.
