Ontario RAT-1A handle scales

In 2008–2009, Ontario Knife Company—partnered with Randall’s Adventure & Training (RAT)—introduced the RAT-1A (model series like 8870/8871) as the assisted-opening evolution of the iconic RAT-1 (manual liner lock, debuted 2003). Responding to demand for faster deployment in tactical and survival scenarios, Ontario added their patent-pending Tactical Assisted Opening (T.A.O.) mechanism—spring-assisted via thumb stud—for lightning-fast one-hand operation while retaining the RAT-1's proven ergonomics and durability

The Ontario RAT-1A features a 3.625-inch drop-point blade in AUS-8 stainless steel (satin or black-coated, later variants in D2/S35VN) for corrosion resistance and slicing, with the same index finger groove, jimping, textured Zytel or G-10 handles (black, orange, desert tan), ambidextrous thumb studs, 4-way reversible clip, and liner lock—ideal for tactical EDC knives, survival folders, and hard use

Priced affordably (~$60–$90 MSRP, USA/China-made), it earned praise for smooth assist, reliable lockup, and value—quickly becoming a bestseller and modern classic. Variants (plain/serrated, G-10 scales, colors) followed, solidifying the RAT-1A as a benchmark in assisted-opening tactical folders and Ontario's RAT legacy of rugged, field-proven performance
