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 Hippo-RLYM JM15-RLYM-14: 14C28N Stainless Steel Performance, Specs and Honest Review

The Hippo-RLYM JM15-RLYM-14 is Trivisa's full-size everyday folder: a 3.4-inch (86.3 mm) 14C28N stainless swedge blade with a stonewashed finish, hardened to 60±2 HRC, riding on ceramic ball bearings. A crossbar lock keeps fingers out of the closing path, and the orange-blue swirl Micarta handle gives a confident, secure grip. At 7.93 inches (201.4 mm) overall and 146.3 g, it is a serious working folder that still disappears into a front pocket - see the full Trivisa knives lineup for the rest of the family.

Why 14C28N Works on a Hippo-RLYM-Class Folder

Sandvik 14C28N is a nitrogen-alloyed Swedish stainless that excels exactly where a daily-carry knife lives: wet pockets, food prep, cardboard, rain. It resists corrosion better than D2 or 154CM, takes a razor edge in minutes on any stone, and its fine carbide structure resists chipping when a cut goes sideways. If you want maximum edge life instead, compare it against M390 steel or Nitro-V in our steel guides; if you want a knife you can use hard and maintain cheaply, 14C28N is the honest answer - browse all 14C28N knives to see the competition.

Why the Hippo-RLYM JM15-RLYM-14 Belongs in Your Pocket

• 3.4-inch 14C28N swedge blade at 60±2 HRC - corrosion-resistant, chipping-resistant and fast to sharpen.
• stonewashed finish - a mottled low-glare tumble finish that hides scratches better than any coating
• orange-blue swirl Micarta handle - a marbled orange-and-blue swirl laminate - every handle pattern is unique
• Crossbar lock - ambidextrous, keeps fingers out of the blade path and locks up solid with zero blade play.
• Ceramic ball bearing pivot - low-friction, rust-proof action that flicks open with a light wrist movement.
• 146.3 g full-size build - 7.93 in open / 4.53 in closed with a 0.14 in blade for stiff, confident cuts.
• Thumb stud + pocket clip - one-handed opening and deep, discreet carry straight out of the box.

Best Uses for the Hippo-RLYM JM15-RLYM-14

• Everyday carry: breaking down boxes, opening packages, lunch prep and the hundred small cuts a workday produces.
• Hiking: a 146 g folder that handles trail snacks, cordage and feather sticks without weighing the pack down.
• Camping: food prep and camp chores where the corrosion resistance of 14C28N earns its keep in damp conditions.
• Fishing: cutting braid and line, and a blade that rinses clean after saltwater exposure without pitting.
• Gifting: a sub-$75 folder with premium action and finish that reads far above its price on unboxing.

Frequently Asked Questions

Is 14C28N a good steel compared to D2?
For pocket carry, yes. D2 holds an edge longer in dry abrasive cutting, but it is only stain resistant, pits if neglected, and is noticeably harder to sharpen. 14C28N trades a little edge life for corrosion resistance and toughness, which matter more in a knife that gets used wet.

What is a crossbar lock and why prefer it?
A spring-loaded bar slides across the blade tang and locks it open. It is fully ambidextrous and keeps your fingers out of the closing path - safer to disengage than a liner lock and immune to spine-pressure failure.

How does the carbon fiber + G10 handle differ from Micarta?
The CG-14 pairs a carbon fiber scale with G10 for a stiff, gloss-textured panel; the Micarta versions grip harder when wet and develop a patina. Both are moisture-proof; it is a feel and aesthetics choice.

Does the rose gold PVD finish wear off?
Any coating wears first along the edge bevel and the clip contact points after long use. That wear is cosmetic; 14C28N underneath is equally stainless.

Is this knife suitable for left-handers?
Yes. The crossbar lock and thumb-stud opening are fully ambidextrous, and the clip can be repositioned with a Torx driver.

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 and a distinctive angular Hippo silhouette.

Hippo JM15
Trivisa's full-size crossbar-lock folder: a 3.4 inch 14C28N swedge blade, ceramic bearing pivot, 7.93 inches overall and 146.3 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.

Crossbar Lock
A spring-loaded bar that slides across the blade tang to lock it open. Ambidextrous, keeps fingers out of the blade path when closing, and cannot disengage under spine pressure the way a liner lock can.

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.

Swedge
A false edge ground along the blade spine. It lightens the blade, sharpens the profile visually and improves penetration without adding a second cutting 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.

Thumb Stud
A pair of posts threaded into the blade that catch the thumb for one-handed opening. Faster than a hole on a stiff detent, but they sit in the way when you sharpen near the plunge line.

Micarta
Fabric or paper laminate set in phenolic resin. It grips when wet, does not shrink, and develops a patina from hand oils - the reason it has been a knife-handle standard for a century.

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.

Who Should Buy the Hippo-RLYM JM15-RLYM-14

• You want a full-size 3.4 inch folder at a working price with premium action.
• You use your knife daily and want a steel that sharpens back in minutes.
• You are left-handed and tired of liner locks designed for right hands only.
• You need a rust-proof blade for fishing, camping or humid climates.
• You want a standout finish - rose gold PVD, green Micarta or swirl Micarta - without paying collector prices.

Who Should Skip It

• You want maximum edge retention. M390 or S35VN folders out-cut 14C28N in dry cardboard.
• You want a sub-3 oz knife. At 146.3 g this is a full-size tool, not a featherweight.
• You need a 4 inch blade for heavy camp chores - look at the fixed blade or larger Bestech options instead.
• You are a collector chasing limited editions. This is a user knife, priced like one.

Care & Maintenance

• Wipe the blade dry after every use; 14C28N is genuinely stainless, but pocket lint holds moisture against the steel and pits it over months.
• One drop of light knife oil at the pivot monthly, then pull the crossbar and swing the blade a dozen times so the oil reaches the ceramic bearing.
• Keep the crossbar track clean. Blow lint and grit out of the channel before oiling, or the bar starts to feel notchy and hangs halfway open.
• Do not over-torque the pivot. 14C28N at 60 HRC wants a free-swinging blade; a crushed bearing race will not fix itself.
• Sharpen on a 1000-grit water stone or a diamond plate at 15-18 degrees per side. 14C28N grinds fast and takes a keen edge in minutes - no diamond required.
• Finish on a loaded leather strop with light pressure, and skip pull-through carbide sharpeners entirely; they remove more steel than they restore.
• Wipe the swirl Micarta scales with a barely damp cloth and dry immediately; the marbled pattern is solid laminate, not a print.
• Clean textured handle scales with warm water and a soft brush. Solvents dry out the resin in Micarta and dull the sheen of carbon fiber.
• Check the clip and body screws every couple of months with the correct Torx driver, and never pry or twist the 3.5 mm blade - the tip is a cutter, not a lever.
