Spyderco Ladybug Black Plain Edge Knife
It attaches to your keychain and is nearly as small as your car keys. One of Spyderco's smallest lightweight locking knife is the Ladybug.
Made of VG-10 stainless steel, the hollow ground blade comes in a SpyderEdge or PlainEdge configuration. This modified clip-point blade style is matched up with a black, lightweight handle of fiberglass-reinforced nylon resin making the entire knife weigh only 0.6 of an ounce (16.4 grams). The LBK3 doesn't have a clip but rather a lanyard hole for attachment to a keychain or lanyard.
Like its larger counterparts (and all Spyderco knives) the Ladybug3 packs tremendous cutting power and can take on both fine and heavy cutting tasks.
