What steel is used in the Tenable Prometheus T1040A3?
The Tenable Prometheus T1040A3 uses 14C28N steel. Sandvik 14C28N is a fine-grained stainless steel prized for its keen edge, good edge retention, and strong corrosion resistance, and the stonewashed finish helps hide scratches and resist glare.
What handle material does the Tenable Prometheus T1040A3 have?

What lock type does the Tenable Prometheus T1040A3 use?
The Tenable Prometheus T1040A3 uses a liner lock. A liner lock uses a spring-tensioned steel liner that snaps behind the blade tang to hold it open, allowing quick and reliable one-hand opening and closing.
What is a sheepfoot blade?
A sheepfoot blade, as featured on the Tenable Prometheus T1040A3, has a straight cutting edge with a rounded, dull spine that curves down to meet the tip. This design gives excellent control for slicing and push cuts while reducing the risk of accidental punctures.
Is the Tenable Prometheus T1040A3 a good EDC knife?
Yes — the Tenable Prometheus T1040A3 pairs a compact 3.29" blade with smooth ceramic ball-bearing action and a comfortable blue Micarta handle, making it a capable and stylish everyday carry at a great value.
