A stonewashed finish complements the blade, while the carbon fiber and G10 handle provides a distinctive, functional grip. The ceramic ball-bearing pivot supports smooth opening, and the crossbar lock secures the blade when in use. Measuring 6.96 inches overall and 3.97 inches closed, this knife weighs just 2.69 ounces. With a blade hardness of 60±2 HRC, it is suited to EDC, hiking, camping, fishing, and hunting tasks.

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 Koala Plus-CG - Stonewash 14C28N Drop Point on a Carbon Fiber + G10 Handle

The Trivisa Koala Plus-CG JM13-CG-14 pairs a stonewash 14C28N drop point with a marbled carbon fiber + G10 handle, locked by an ambidextrous crossbar lock on ceramic bearings at 76.3 g. Compact folding knife built for real carry - more EDC gear at EDCMALL.

Sandvik 14C28N - The Low-Maintenance Steel Done Right

The Koala Plus-CG runs 2.99 inches of Sandvik 14C28N at 60+/-2 HRC under a stonewash tumble. Nitrogen alloying keeps the grain fine and the steel tough, so the edge resists chipping when you twist out of a cut, ignores rain and sweat, and comes back to shaving sharp on a basic stone in minutes. It gives up a half-step of raw edge life to super steels - and in exchange you never think about rust. The handle is a carbon fiber and G10 composite laminate: carbon fiber's marbled depth with G10's grip and impact tolerance, sealed against moisture. Compare 14C28N with D2, Nitro-V and 154CM in the table below.

Frequently Asked Questions

What steel is the Koala Plus-CG blade?
Sandvik 14C28N stainless at 60+/-2 HRC with a stonewash finish. It is corrosion-resistant, chip-resistant and famously easy to sharpen.

How does the crossbar lock work?
A spring-loaded bar wedges behind the blade tang when the knife opens. Pull the bar back to release the blade - your fingers stay out of the blade path the whole time, and it works equally from either hand.

Is the handle real carbon fiber?
It is a carbon fiber + G10 composite laminate - woven carbon layers pressed with G10 epoxy, giving the look of carbon fiber with the grip and durability of G10.

How big is it?
6.96" (176.7 mm) open, 3.97" (100.7 mm) closed, 2.99" (76 mm) blade at 0.11" (3 mm) thick, 76.3 g (2.69 oz) - a compact everyday folder with full-size cutting reach.

Is it left-hand friendly?
Yes. The thumb stud, crossbar lock and blade geometry all work from either hand; only the pocket clip is set for right-hand carry.

Sandvik 14C28N vs. Common Pocket Knife Steels

Steel	Typical HRC	Edge Retention	Corrosion Resistance	Toughness	Sharpening Ease
14C28N (this knife)	59-61	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
D2 Tool Steel	58-61	Very Good	Fair	Good	Moderate
8Cr13MoV	57-59	Fair	Good	Good	Very Easy

Sandvik 14C28N is a nitrogen-refined martensitic stainless that lands at 58-61 HRC in production heat treats. On a value folder it is the smart pick: corrosion resistance that survives wet weather and pocket sweat, a fine stable edge that refuses to chip, and sharpening so easy a few passes on a pocket stone restore the apex. The trade is raw wear resistance - expect more frequent touch-ups than a high-vanadium super steel under abrasive cardboard work. 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.

Koala Plus-CG
Trivisa's compact crossbar-lock folder: a 2.99 inch 14C28N drop point on a carbon fiber + G10 composite handle, ceramic bearings, 76.3 g.

Sandvik 14C28N
A nitrogen-alloyed martensitic stainless at 58-61 HRC. Corrosion-proof, fine-grained, hard to chip and famously easy to sharpen.

Drop Point
A blade profile whose spine slopes down to the tip, leaving a deep belly for slicing and a strong point protected by the drop.

Machined Fuller
The long groove milled into the blade flat. It removes weight ahead of the pivot, stiffens the blade for its thickness and breaks up the silhouette.

Crossbar Lock
A spring-loaded bar spanning the handle that wedges behind the blade tang. Fully ambidextrous, keeps fingers out of the closing path, and among the strongest folder locks built.

Ceramic Ball Bearings
Hardened ceramic balls around the pivot. The action stays glassy for years, and ceramic will not rust or flat-spot.

Carbon Fiber
Woven carbon cloth cured in resin: rigid, extremely light and immune to humidity, with a depth of pattern no plain polymer can match.

G10 Scales
Fibreglass laminate pressed with epoxy. Practically indestructible, moisture-proof and textured for grip even when wet.

Stonewash Finish
A tumbling process that beads the steel into a uniform matte grey, hiding carry scratches and killing glare far better than satin.

60+/-2 HRC
The Rockwell C hardness band the blade is heat treated to: hard enough for long edge life, still honest to sharpen at home with patience.

Thumb Stud
A small post on the blade spine that the thumb pushes to open the knife one-handed. Simple, snag-free and fully ambidextrous.

Who Should Buy the Koala Plus-CG

• Carriers who want a low-maintenance stainless blade they can abuse in rain and sweat.
• Fans of crossbar locks who want fidget-safe one-hand action on a budget.
• Anyone who wants carbon fiber looks without carbon fiber fragility.
• Compact-EDC buyers who still want a full 2.99 inch cutting edge.
• Gift buyers shopping for a well-built sub-$70 folder.

Who Should Skip It

• Super-steel chasers - 14C28N trades edge life for toughness and easy sharpening.
• Hard-use prying and batoning - 3 mm stock is a slicer, not a pry bar.
• Buyers who want premium titanium or M390 at this price - see the Trivisa Skarn instead.
• Users who want a flipper tab - the Koala opens by thumb stud only.

Care & Maintenance

• Wipe the blade dry after every use; 14C28N is genuinely stainless, but pocket lint holds moisture against the steel.
• One drop of light knife oil at the pivot monthly, then swing the blade a dozen times so oil reaches the ceramic bearing.
• To close it, pull the crossbar lock back and let the blade fall or swing shut - keep fingers out of the blade path.
• Blow pocket lint out of the handle channel and the lock-bar track before oiling so grit never grinds the pivot.
• Sharpen on a 1000-grit water stone or diamond plate at 15-18 degrees per side; 14C28N grinds fast and takes a keen edge in minutes.
• Finish on a loaded leather strop with light pressure - heavy passes round the apex you just set.
• Wipe the carbon fiber + G10 composite scales with a damp cloth; the sealed laminate needs no oiling or special care.
• Check the pocket clip and body screws every month or two with the correct Torx driver; pocket carry backs them out.
• Never pry, twist or use the 3 mm blade as a screwdriver - the tip is a cutter, not a lever.
