Overview
A Gerber knife with a 1.8 inch stainless steel blade and 3.6 inch overall length, weighing 2.9 ounces. The handle is fiberglass. It holds a 4.5 rating across nearly 8,935 reviews.
At under 4 inches overall and under 3 ounces, this reads as a small everyday carry blade rather than a working or outdoor knife built for heavier tasks. The fiberglass handle keeps weight down while the stainless blade resists corrosion, a pairing suited to pocket carry rather than field or kitchen work.
