This TR-5 automatic Operator model has a black anodized aluminum handle with a black back spacer/lanyard attachment, and a deep carry tip-up pocket clip. Its blade is made from CPM-S35VN stainless steel in a black finish. In Operator fashion, the push button has a tritium vial inlay and no branding anywhere on the knife. A sliding safety lock allows secure pocket carry and prevents accidental blade deployment. Pro-Tech has added an automatic option to their TR-5 line. Similar in design to the TR-4 auto, the TR-5 is smaller and more pocket-friendly.
