This Benchmade Panther Lightweight 401? or 405? Not sure of the model number. This pocketknife is a great addition to any collection. The knife features a 3 1/4in. ATS-34 blade with a plain edge and drop point blade type. The black Zytel handle material complements the sleek design of the knife, making it a stylish and functional tool. The manual opening mechanism and liner lock type ensure safety and ease of use. This original Benchmade knife is from the United States and is part of the Benchmade Panther product line. With its high-quality blade material and exceptional design, this knife is perfect for everyday use or as a collectible item. This knife may have been used.  The backside of the blade looks like it may have been cleaned with a scotchbrite. It does have some storage wear like handling marks and some dirt build up and some specks that may be some corrosion. If you have any questions, just ask, I check my eBay all the time.
