Product Description
The Ontario RAT 1 is one of the most proven working folders in its class — a straightforward linerlock that has earned a loyal following through reliable performance and honest value. This S35VN variant replaces the standard AUS-8 with CPM-S35VN stainless steel, bringing meaningful gains in edge retention and corrosion resistance without sacrificing the toughness the RAT 1 is known for. The stonewash finish on the 3.5-inch drop point blade hides everyday wear and resists scratching through hard carry.
The forest green G10 handle offers the RAT 1's familiar ergonomics in a subdued field color — G10's texture provides a secure grip in wet or dry conditions. Steel liners add rigidity and the linerlock engages quickly and reliably. Ambidextrous thumb stud deployment, tip-up/tip-down pocket clip, and a lanyard hole give full carry flexibility. The RAT 1 has built its reputation as a go-to workhorse — the CPM-S35VN version just holds that edge longer. Available at Knifeworks with same or next business day shipping.
