Designed by the TRIVISA team, the Batwing-YP JM10S-YP-14 combines a compact profile with practical everyday versatility. Its 2.99-inch sheepfoot blade is made from 14C28N stainless steel, a low-maintenance choice valued for corrosion resistance and easy sharpening. A sandblasted finish completes the blade, while the lightweight PEI handle and ceramic ball bearings support comfortable handling and smooth opening. The crossbar lock secures the blade during use. Measuring 6.7 inches overall and 3.7 inches closed, this folding knife weighs just 2.39 ounces for convenient carry. The blade is 0.11 inches thick, with a stated hardness of 60±2 HRC. Suitable for everyday carry and outdoor activities such as hiking, camping, fishing, and hunting, it offers a practical, portable design.

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 Batwing-YP - Sandblast 14C28N Sheepfoot on a Translucent Yellow PEI Handle

The Trivisa Batwing-YP JM10S-YP-14 pairs a sandblast 14C28N sheepfoot with translucent yellow PEI scales, opened by thumb hole and locked by an ambidextrous crossbar lock at just 68 g. Ultralight folding knife for daily EDC - EDCMALL.

A 68-gram Folder That Still Carries a Real 2.99 Inch Edge

The Batwing-YP is the light knife in Trivisa's line done properly: 2.99 inches of Sandvik 14C28N at 60+/-2 HRC with a sandblast finish on 3 mm stock, riding in translucent yellow PEI scales. 14C28N is nitrogen-alloyed for toughness and corrosion resistance - it shrugs off rain, sweat and river spray and sharpens back to keen in minutes on a basic stone. PEI (polyetherimide) is an engineering polymer that is rigid, heat-resistant and chemically inert, and here it is translucent, so the hardware glows through the yellow scales. The sheepfoot profile puts the point low and under fingertip control, the safest shape around fingers and food. Compare 14C28N with D2, Nitro-V and 154CM below.

Why the Trivisa Batwing-YP Belongs in Your Pocket

• 2.99 inch (76 mm) Sandvik 14C28N sheepfoot at 60+/-2 HRC on 3 mm stock.
• Sandblast finish - matte, glare-free and scratch-hiding.
• Translucent yellow PEI scales with orange accents - light glows through.
• Thumb-hole opening on ceramic ball bearings - fast and snag-free.
• Ambidextrous crossbar lock, the strongest folder lock class.
• 68 g total with a 3.7 inch closed handle - barely there in the pocket.
• Jimped thumb ramp for controlled push cuts.
• Low-point sheepfoot tip that is the safest profile around fingers and food.

Best Uses for the Batwing-YP

• Ultralight EDC for runners, hikers and gram counters.
• Kitchen-adjacent tasks - the sheepfoot tip is the safest around fingers and food.
• Wet-weather carry: stainless blade plus moisture-immune polymer scales.
• Office carry where the translucent yellow handle reads friendly, not tactical.
• Backup blade in a pack, boat bag or fishing vest.

Frequently Asked Questions

What is the handle made of?
Translucent yellow PEI (polyetherimide), a high-performance engineering polymer: rigid, heat-resistant, chemically inert and lighter than G10.

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

How does the thumb hole open the knife?
Press the cut-out near the spine with your thumb; the blade swings open on ceramic bearings and the crossbar lock snaps behind the tang.

Is the crossbar lock safe?
It is among the strongest folder locks built: a bar wedges behind the blade tang, works from either hand and keeps fingers out of the closing path.

How light is it really?
68 g (2.39 oz) at 6.7" (171 mm) open - one of the lightest 2.99 inch folders we 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.

Batwing-YP
Trivisa's compact crossbar-lock folder: a 2.99 inch 14C28N sheepfoot with a sandblast finish on translucent yellow PEI scales, thumb-hole opening, ceramic bearings, 68 g.

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

Sheepsfoot Blade
A blade whose spine curves down to meet a mostly straight edge, leaving a fine, controllable point. Safest around fingers.

PEI (Polyetherimide)
A high-performance engineering polymer (ultem family): rigid, heat-resistant, chemically inert and translucent, so light glows through the scales. Lighter than G10 and immune to moisture.

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.

Thumb-Hole Opening
A cut-out near the blade spine where the thumb presses to swing the blade open one-handed - no flipper tab to snag in the pocket.

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.

Who Should Buy the Batwing-YP

• Gram counters who refuse to give up a full 3 inch edge.
• Anyone who wants the safest blade shape for food prep and finger work.
• Wet-climate carriers - 14C28N plus PEI simply does not care about rain.
• Left-handed users - thumb hole and crossbar lock are fully ambidextrous.
• Buyers who want unusual translucent handles that glow in daylight.

Who Should Skip It

• Piercing tasks - the low sheepfoot point is deliberately weak for tip work.
• Super-steel chasers - 14C28N trades edge life for easy care and toughness.
• Hard-use prying - 3 mm stock and polymer scales mark a slicer, not a pry bar.
• Buyers who prefer premium titanium - the Skarn is Trivisa's titanium flagship.

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 swing the blade shut with a flick on the thumb hole - 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.
• Rinse the PEI scales with warm water if they get grimy; the polymer is chemically inert and needs no oil or wax.
• 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.
