14C28N Blade Introduction

14C28N is a high-value budget-to-midrange stainless steel that excels in corrosion resistance and ease of sharpening, making it a low-maintenance workhorse for EDC and wet environments, but it falls short of premium steels in edge retention and requires more frequent touch-ups when cutting highly abrasive materials like cardboard.

SPECIFICATIONS

Tenable Rango B1120A3 - Product Overview

The Tenable Rango B1120A3 is Steven Kastner's geometry-driven EDC folder: a 3.41-inch 14C28N sheepfoot blade with rounded safe tip, a weight-saving fuller and the Mohawk flipper that snaps the blade open with a thumb press along the spine. black aluminum scales carry Kastner's mosaic-inspired facet pattern, and the liner lock keeps everything secure at 4.26 oz and 7.92 inches overall. A distinctive, art-directed folder inside the Tenable Knives lineup that still earns its pocket time in everyday carry.

Tenable Rango B1120A3 - 14C28N Blade Performance

14C28N is the smart money in modern EDC steel. Sandvik's nitrogen-alloyed stainless runs 59-61 HRC with excellent corrosion resistance and the easiest sharpening of any steel in the store: ten passes on a ceramic rod restore a working edge, so maintenance never becomes a project. The fine, stable edge it takes is exactly what cardboard, rope, food and daily slicing tasks want, and in wet weather it shrugs off corrosion that would speckle lesser steels.

Frequently Asked Questions

What is a Mohawk flipper?

A flipper tab that rides along the spine ahead of the pivot instead of hanging below the handle. Press it down with your thumb and the blade snaps open - with nothing protruding into the cutting path or pocket.

Why choose a sheepfoot blade?

The straight edge and rounded tip give maximum control for slicing on flat surfaces and near-zero accidental puncture risk - ideal for food, boxes and careful work.

How does 14C28N hold an edge?

It holds a good working edge for a value steel - shorter than super steels like M390, but it re-edges in minutes on a ceramic rod, so upkeep is trivial.

Does the Damascus version need special care?

Yes - wipe it dry and oil it occasionally, especially in humid weather. The water ripple pattern is unique to your exact blade.

Is the geometric pattern just cosmetic?

On aluminum it is milled texture that adds grip; on G10 it is layered laminate texture. Either way the facets give your fingers real purchase.

Tenable Rango B1120A3 - Who Should Buy / Who Should Skip

Who Should Buy

• Sheepfoot fans who slice more than they pierce
• Design-forward carriers who want geometry that stands out
• Kitchen-adjacent EDC users - the sheepfoot profile excels on boards
• Kastner design collectors completing the Rango quartet
• Anyone who wants safe-tip confidence around pets, kids and crowds

Who Should Skip

• You need a piercing point - the sheepfoot tip is deliberately rounded
• You want a featherweight; 4.26 oz is full-size territory
• You want premium super steel; 14C28N and Damascus are value steels
• You prefer thumb studs - the Mohawk flipper replaces them
• You want aggressive tactical styling; the Rango is art-forward, not tactical

Tenable Rango B1120A3 - Care & Maintenance

1. Wipe the blade dry after use - 14C28N is highly corrosion-resistant but not immune to pocket sweat.
2. One drop of quality knife oil at the pivot monthly, then cycle the action to spread it.
3. Sharpen on a ceramic rod or fine stone; the steel re-edges in minutes, no diamond plate needed.
4. Rinse with warm water and mild soap after food or salty tasks, then dry thoroughly.
5. Anodized aluminum scales: clean with a damp cloth only - solvents dull the finish.
6. G10 scales: wash with warm soapy water and a soft brush; the texture releases dirt easily.
7. Keep the lock bar contact area free of lint so lockup stays tight and consistent.
8. Never pry or twist the tip; sheepfoot geometry is tough but the thin flat grind is not a lever.
9. Re-torque clip and body screws periodically with the correct Torx driver.
