Nitro-V Blade Introduction

Nitro-V is a nitrogen-enriched martensitic stainless steel refined to deliver an outstanding balance of extreme toughness, fine edge stability, and excellent corrosion resistance. Its fine carbide structure allows for remarkable ease of sharpening and exceptional resistance to chipping. However, its edge retention is modest when compared to high-vanadium powder metallurgy steels, meaning it requires more frequent honing under abrasive cutting tasks. It is an ideal choice for demanding applications where durability and ease of maintenance outweigh ultimate wear resistance.

SPECIFICATIONS

Tenable Riflestock B2131S4 - Product Overview

The Tenable Riflestock B2131S4 distills retired officer Nick Swan's duty experience into a slim gunstock-pattern folder: a 2.34-inch Nitro-V blade on a flat grind, olive green G10 scales scales and a proven lock back mechanism. At 5.48 inches overall and just 1.66 oz, it is the rare knife that carries lighter than it looks, with checkered gunstock texturing borrowed straight from rifle furniture. Built to work, not to shelf-sit - a genuine everyday folding knife for carriers who value reliability over flash, backed by EDC-ready fit and finish.

Tenable Riflestock B2131S4 - Nitro-V Blade Performance

Nitro-V is the working carrier's steel: a nitrogen-alloyed martensitic stainless that trades a little ultimate edge retention for noticeably better toughness, chip resistance and sharpening ease. At 59-61 HRC a ten-minute touch-up on a ceramic rod returns a genuinely keen working edge, and the fine carbide structure resists the micro-chipping that ruins harder steels on boxes, cord and bone. For a knife meant to be used every day and maintained in minutes, it is one of the smartest choices in the store.

Frequently Asked Questions

What is a lock back lock?

A spine-mounted lever snaps into a notch cut in the blade tang when the blade opens. It is one of the oldest and strongest folder locks - release by pressing the lever on the spine while closing.

Why is the Riflestock so light?

Slim 3.0 mm blade stock, compact 2.34-inch blade and thin scales keep it at 1.66 oz. It is designed for carry comfort first.

Does the Damascus version need special care?

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

Is the gunstock texture actually grippy?

Yes - the checkered pattern is milled into the scales, adding real traction even with wet hands, and it is the design's signature look.

How does Nitro-V compare to 14C28N or D2?

Nitro-V is tougher and easier to sharpen than D2, with edge retention close to 14C28N - the balance point for a small working blade.

Tenable Riflestock B2131S4 - Steel Comparison Table

Glossary of Key Terms

Lock Back
A spine-mounted locking lever that snaps into a notch cut in the blade tang. Proven, rock-solid, and it keeps the release stroke well away from the edge.

Gunstock Pattern
The checkered, angled texturing borrowed from rifle stocks - milled into the scales for grip and a nod to Nick Swan's firearms background.

Nick Swan
Retired law-enforcement officer turned designer; his Tenable knives are engineered for real-world duty, not display cases.

Nitro-V
A nitrogen-enriched martensitic stainless at 59-61 HRC: excellent toughness, fine edge stability and very easy sharpening.

Water Ripple Damascus
Pattern-welded steel etched to show flowing water-like lines. No two blades pattern the same; oil it occasionally.

Gray TiCn Coating
Titanium-carbonitride vapor-deposited layer: harder than the steel beneath it, low-friction and neutral gray instead of glossy black.

Twill / Shred Carbon Fiber
Two CF weaves - twill is the classic 2x2 diagonal; shred is chopped-fiber collage. Both are light, rigid and immune to humidity.

Tenable Riflestock B2131S4 - Who Should Buy / Who Should Skip

Who Should Buy

• Minimalist carriers who want sub-2 oz without losing real capability
• First-time quality-knife buyers at an accessible price
• Nick Swan followers collecting the Riflestock line variants
• Office and front-pocket carriers who need a slim, quiet folder
• Anyone who prefers a lock back's bombproof simplicity

Who Should Skip

• You want a 3.5-inch-plus blade; the Riflestock runs a compact 2.34 inches
• You want flipper or stud deployment - the lock back opens two-handed
• You want a super steel; Nitro-V and Damascus are honest work steels
• You want heavyweight hard-use build; this is deliberately slim at 1.66 oz
• Left-hand dominant users - the lock back release is right-hand biased

Tenable Riflestock B2131S4 - Care & Maintenance

1. Wipe the blade dry after every use; Nitro-V resists rust well but pocket sweat will still spot bare steel over time.
2. One drop of quality knife oil at the pivot monthly, then cycle the action so it spreads through the bearings or washers.
3. Blow pocket lint out of the handle channel and around the button lock before oiling so grit never grinds in the pivot.
4. Sharpen on a coarse-to-fine waterstone or diamond plate; Nitro-V grinds easily and takes a scary-sharp edge fast.
5. Finish on a loaded strop - light pressure only, because heavy passes round the apex and dull the edge you just set.
6. Rinse with warm water and mild dish soap when grimy, then dry thoroughly before it goes back in the pocket.
7. Never pry or twist with the tip; the clip point is a slicer first and hard steel trades impact toughness for wear resistance.
8. Check the reversible clip screws periodically with the correct Torx driver so the knife never rides loose in the pocket.
9. If the GITD or foil-pattern scale gets scuffed, a gentle melamine-sponge pass evens the sheen without eating the laminate.
