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.

Trivisa Hummingbird-BG JM07-BG-14: 14C28N Stainless Steel Performance, Specs and Honest Review

The Hummingbird-BG JM07-BG-14 is Trivisa's compact everyday folder: a 2.9-inch (75.3 mm) 14C28N drop point blade with a stonewash finish, hardened to 60±2 HRC, on a ceramic ball bearing pivot. A liner lock secures the blade, and the black G10 handle keeps the whole knife at just 76 g. It measures 6.7 inches (170 mm) open and 3.8 inches (95.6 mm) closed - small enough to forget, sharp enough to rely on, and a clear standout in the Trivisa knives range.

Why 14C28N Suits a Small Folder

A small blade gets used for everything and sharpened rarely, so the steel has to be forgiving. Sandvik 14C28N resists corrosion better than D2 or 154CM, takes a keen edge in minutes on any stone, and its fine carbide structure resists the micro-chipping that thin small blades suffer. Compared with the M390 steel used in Trivisa's premium folders it gives up edge life and buys toughness and stain resistance - the right trade at this price.

Why the Hummingbird Belongs in Your Pocket

• 2.9-inch 14C28N drop point at 60±2 HRC - a versatile, chip-resistant edge for daily cutting.
• Stonewash finish - hides scratches and fingerprints better than any polished or coated surface.
• Black G10 scales - aggressive texture, moisture-proof, and virtually indestructible.
• Liner lock - simple, ambidextrous lockup with easy one-hand closing.
• Ceramic ball bearing pivot - buttery flick-open action with no washer break-in.
• Just 76 g - a 6.7 in folder that vanishes in a pocket and carries a rope hole for a lanyard.
• Spine jimping - confident thumb placement on push cuts.

Best Uses for the Hummingbird-BG JM07-BG-14

• Office carry: a non-threatening size for packages, envelopes and lunch prep.
• Everyday errands: 76 g disappears into gym shorts or a jacket pocket without a print.
• Hiking day trips: trail snacks, cordage and small repair cuts with a drop point that handles them all.
• Fishing: braid and leader work, and a stainless blade that shrugs off spray.
• First serious knife: a sub-$50 folder with bearing action and quality steel - an ideal gateway into EDC.

Frequently Asked Questions

Is the Hummingbird small enough for legal pocket carry everywhere?
At 2.9 inches of blade and 76 g it is squarely in the 'small folder' category most jurisdictions treat leniently. Always check your local rules.

How does 14C28N compare to D2 or 8Cr13MoV at this price?
It is a clear step up from 8Cr13MoV in corrosion resistance and edge stability, and a smarter pick than D2 for a knife that lives in a humid pocket and gets used wet.

Is the liner lock safe?
Yes - lockup is early and solid on this model, and the stainless liner is full length. Keep the lock face dry and free of grit per the care section.

Is the clip reversible?
Yes, the clip unscrews for left- or right-hand tip-up carry with a correctly sized Torx driver.

What is the rope hole for?
Knot a lanyard or paracord through it for faster retrieval from a pocket or bag, or to add a fob that makes the small handle fill the hand.

Sandvik 14C28N vs. Common Pocket Knife Steels

Steel	Typical HRC	Edge Retention	Corrosion Resistance	Toughness	Sharpening Ease
14C28N (this knife)	58-61	Good	Excellent	Good	Very Easy
Nitro-V	59-61	Good	Very Good	Better	Easy
154CM	58-61	Good	Good	Very Good	Moderate
CPM-S35VN	58-60	Very Good	Very Good	Better	Moderate
Bohler M390	60-62	Excellent	Excellent	Fair	Hard
D2 Tool Steel	58-61	Very Good	Fair	Good	Moderate
8Cr13MoV	57-59	Fair	Good	Good	Very Easy

Sandvik 14C28N is a nitrogen-alloyed martensitic stainless that lands at 58-61 HRC in a production heat treat. It gives up a step of raw wear resistance to D2 and CPM-S35VN and takes back corrosion resistance and edge stability that is very hard to chip - which is why it is the default choice for a knife that gets used wet, dirty and often. It grinds fast on any stone and takes a keen polished edge in minutes. HRC figures are typical mill ranges, not a guarantee for any single blade.

Glossary of Key Terms

Trivisa
A Chinese knife brand building premium-steel folders with a clean in-house design language.

Hummingbird JM07
Trivisa's compact liner-lock folder: a 2.9 inch 14C28N drop point in stonewash, black G10 scales, ceramic bearing, 76 g.

Sandvik 14C28N
A nitrogen-alloyed Swedish martensitic stainless from Alleima (formerly Sandvik). It trades a step of wear resistance for excellent corrosion resistance and edge stability that resists chipping, and it sharpens in minutes on any stone.

Liner Lock
A spring-steel liner inside the handle presses against the blade tang to keep it open. Simple, ambidextrous in most designs, and easy to clean, which is why it remains the default on traditional folders.

G10
Woven fiberglass cloth laminated in epoxy resin. It is nearly immune to moisture, extremely strong for its weight, and can be layered in colours so the edges show stripes - the effect used on the Bestech Fin handles.

Stonewash Finish
The blade is tumbled with abrasive media to produce a mottled, low-glare surface. It hides scratches better than any other finish and does not show fingerprints.

Ceramic Ball Bearing Pivot
A pair of ceramic balls running in steel races between the blade and the handle. Lower friction than washers, immune to rust, and unaffected by the grit that eventually fouls a phosphor-bronze washer.

Jimping
Small machined notches on the blade spine or lock bar that give the thumb purchase and stop the hand from slipping onto the edge.

HRC (Rockwell C)
The hardness scale used for knife steel. Higher HRC means better edge retention and more brittleness; 58-61 is a working range, 62-64 buys edge holding at the cost of shock tolerance.

Who Should Buy the Hummingbird-BG JM07-BG-14

• You want a genuinely small, light folder under $50 with bearing action.
• You are buying a first real folding knife for yourself or someone else.
• You carry in office or travel settings where a discreet profile matters.
• You use a knife wet - fishing, cooking, rain - and want true stainless.
• You prefer a drop point for its forgiving, versatile tip.

Who Should Skip It

• You want maximum edge retention - M390 or S35VN folders out-cut 14C28N.
• You need a full-size 3.4+ inch blade for camp or farm work.
• You want a titanium handle or premium finishes; this is a tool, priced like one.
• You dislike liner locks and prefer the fumble-free crossbar or button locks.

Care & Maintenance

• Wipe the blade dry after every use; 14C28N resists rust, but salt left on the stonewash finish will spot it over months.
• One drop of light knife oil at the pivot monthly, then open and close the blade a dozen times so oil reaches the ceramic bearing.
• Keep the liner lock face dry. Oil on the lock face lets the bar slide too far across the tang and the blade develops vertical play.
• Blow lint and grit out of the handle channel before oiling so debris never grinds into the bearing race.
• Sharpen on a 1000-grit water stone at 15-18 degrees per side. The 3 mm blade is thin behind the edge, so use light pressure and let the stone do the work.
• Finish on a loaded leather strop with light passes. Skip pull-through sharpeners - they eat more steel than they restore on a blade this small.
• Scrub the black G10 scales with warm water and a soft brush if they get greasy. The texture is solid laminate, so it will not fade or flake.
• Rinse the rope hole after wet outings. Grit lodged in the lanyard port abrades the handle finish when a cord is knotted through it.
• Check the clip and body screws every month or two with the correct Torx driver, and never pry with the 2.9 inch blade.
