The Vero Isotope was Joseph Vero’s first integral folding knife. Milled from one piece of stonewashed titanium, the Isotope is equipped with a 3.9” drop point high flat grind M390 steel blade with a hand satin finish and integral full titanium handle with a warm, yellow brass inlay. Here are some specs. Overall Length: 8.8” (224mm). Closed Length: 4.9” (124.5mm). Blade Length: 3.9” (99.5mm). Blade Thickness: 0.158” (4.0mm). Blade Steel: Böhler M390. Cutting Edge: 3.92” (100mm). Weight: 5.5oz (156g). This knife is in excellent condition. It has never been carried, cut or sharpened while owned by me. Additionally, there is no evidence of cutting or sharpening of the blade at all.
