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.

If you have been waiting for a Nitro-V titanium Tenable Fenrir folder with a proper harpoon tip under $150, this is the one — see how it pairs with the rest of the Tenable Knives lineup.

Steel & Hardware Selling Points

• Nitro-V Stainless: Sandvik's nitrogen-bearing evolution of AEB-L — corrosion resistance to match 14C28N with noticeably improved edge retention and the same easy field-sharpening.
• Harpoon Blade Profile: The aggressive straight-back spine that drops into the cutting edge near the tip concentrates force for pierce-and-slice cuts; a tactical-class geometry that excels at packaging and rope work.

• Titanium Handle: Solid titanium handle gives the knife its premium heft, corrosion-proof durability and that signature cold-metal feel enthusiasts prize.
• Top Liner Lock: Lock bar engages high on the frame so your fingers never apply force to the lock during cutting.

FAQ

Q1. What is Nitro-V steel?
A: Nitro-V is Sandvik's nitrogen-enhanced evolution of AEB-L — stainless, very tough, holds an edge longer than 14C28N and sharpens easily on any stone.

Q2. Why a harpoon blade shape?
A: The straight-back spine narrows dramatically toward the tip, concentrating force for pierce-and-slice cuts. Harpoon blades excel at packaging, rope and aggressive slicing tasks.

Q3. Is titanium heavy?
A: Titanium gives you the heft and feel of a premium folder without the weight of stainless. The Fenrir lands around 4.76oz — noticeable but not burdensome.

Q4. How does the Top Liner Lock work?
A: The lock bar engages near the top of the frame, so your fingers never apply force to the lock during cuts — safer and more reliable than standard liner locks.

Q5. Does it come in other handle variants?
A: Yes — the B1034H series runs titanium (this model) plus G10 and micarta variants on the same Fenrir blade platform.

A straight-back blade profile that swoops into the cutting edge near the tip — built for pierce-and-slice cuts; the classic tactical silhouette.

Top Liner Lock
An upgraded liner lock variant whose bar engages near the top of the frame, isolating the lock from your grip force.

Titanium Handle
Grade-5 titanium scales — corrosion-proof, light, strong, and prized for its cold-metal hand feel.

Who Should Buy / Who Should Skip

Who Should Buy:

• Collectors who want a Nitro-V titanium folder under $150 with a harpoon blade
• Daily carriers in humid or coastal climates needing full corrosion resistance
• Users who prefer harpoon geometry for packaging, food prep and rope cuts
• Premium-EDC gift shoppers looking for a sub-$150 titanium folder from a designer brand
• Tenable Fenrir fans completing the blade-finish and handle-material matrix

Who Should Skip:

• Budget-only buyers — titanium and Nitro-V folders naturally run above the entry-price tier
• Users who prefer lightweight plastic / G10 handles (look at the Entity line)
• Anyone who dislikes aggressive harpoon spine geometry (see drop-point Entity)
• Those who want replaceable utility blades or razor-blade cutters

Care & Maintenance

1. Rinse Nitro-V under fresh water after marine or salty exposure; dry thoroughly.
2. Touch up the blackwash blade on a 1000-grit stone or ceramic rod; Nitro-V sharpens quickly.
3. Wipe the titanium scales with a dry microfiber cloth — no oil needed.
4. Blow lint out of the top liner lock channel periodically for crisp lockup.
5. Add a tiny drop of light oil to the bearing pivot every few months for smooth flips.
6. Check pocket clip screws monthly — titanium threads can gall; back off with thread-locker if needed.
7. Avoid abrasive cleaners on blackwash; they will scrub off the dark patina.
8. Do not pry with the harpoon tip — it is built for pierce-and-slice, not twisting cuts.
9. Store anywhere dry — Nitro-V plus titanium makes this knife essentially maintenance-free.
