Trivisa Skarn-W JM11-W-M M390 Blade Titanium Handle Crossbar Lock Folding Knife

Skarn is named after a rare metamorphic rock formed by intense pressure and transformation, a symbol of strength shaped through process.

A signature design focused on clean geometry, purposeful details, and everyday carry balance. The inside out scale pattern isn’t just visual, it reduces weight, adds grip, and gives the handle a texture you feel every time you pick it up.

An M390 modified tanto blade with a sharp, functional profile is paired with a stylish fuller and thumb stud for smooth, intuitive deployment. Titanium handles, ceramic bearings, and an axis lock complete a knife that’s refined, precise, and made to be used.

M390 Blade Introduction

M390 is an advanced powder-metallurgical stainless steel utilizing high chromium and vanadium content to deliver exceptional wear resistance and industry-leading corrosion resilience. It excels at retaining a razor-sharp edge under prolonged use; however, this extreme hardness renders the blade notably difficult to sharpen or reprofile without diamond abrasives. Additionally, its fine microstructure, while offering superior edge stability, sacrifices some structural toughness and may be more prone to chipping under heavy lateral stress.

Trivisa Skarn-W - Satin M390 Modified Tanto on a Silver Titanium Handle

The Trivisa Skarn-W JM11-W-M by Fabian Hobbelen runs a satin M390 modified tanto with a machined fuller inside an inside-out patterned silver titanium handle, held by an ambidextrous crossbar lock at 100 g. Collector-grade folding knife for serious EDC - EDCMALL.

Bohler M390 Behind a Modified Tanto - Edge Life Meets Piercing Power

The Skarn's 2.87 inch blade is Bohler M390: an Austrian powder-metallurgy stainless in the same class as CPM-20CV and CTS-204P, hardened here to 60+/-2 HRC. Roughly 1.9 percent carbon and 20 percent chromium carbide load give it first-class edge retention and near-saltwater corrosion resistance - weeks of packaging and cord work between touch-ups. The modified tanto point puts a reinforced tip on that long edge, and the machined fuller lightens the blade without thinning the spine. Fabian Hobbelen's inside-out milled scale pattern isn't decoration: it cuts titanium weight, adds grip and gives the hand a texture you feel every pick-up. Compare M390 with CPM-S35VN, 154CM and 14C28N in the table below.

Frequently Asked Questions

What steel is the Skarn blade?
Bohler M390 powder-metallurgy stainless at 60+/-2 HRC with a satin finish. It leads its class in edge retention and corrosion resistance.

Why a modified tanto profile?
The straight primary edge maximizes controlled slicing while the angled tip section puts a strong, pierce-worthy point on the blade - the fuller keeps the weight down.

How does the crossbar lock work?
A spring-loaded bar wedges behind the blade tang when open. Pull the bar back to release; fingers never enter the blade path, and it is fully ambidextrous.

What is the inside-out handle pattern?
A milled recess pattern cut into the titanium scales that reduces weight, adds grip texture and breaks up the flat slabs typical of titanium folders.

Is it hard to sharpen M390?
You need diamond or CBN abrasives rather than ordinary stones, but the edge holds so long that sharpening sessions stay rare.

Bohler M390 vs. Common Folding Knife Steels

Bohler M390 (this knife)	60-62	Excellent	Excellent	Fair	Hard
CPM-20CV	61-62	Excellent	Excellent	Fair	Hard
CPM-MagnaCut	62-63	Excellent	Excellent	Excellent	Moderate
CPM-S35VN	58-60	Very Good	Very Good	Good	Moderate
154CM	58-61	Good	Good	Very Good	Moderate

8Cr13MoV	57-59	Fair	Good	Good	Very Easy

Bohler M390 is an Austrian powder-metallurgy stainless in the same class as CPM-20CV and CTS-204P: roughly 1.9 percent carbon and 20 percent chromium-carbide-forming alloy deliver first-class edge retention and near-saltwater corrosion resistance. Hardened to 60+/-2 HRC, it holds a working edge for weeks of packaging and cord duty, but the dense carbide volume means sharpening wants a diamond plate and the fine apex can chip under prying loads. 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.

Skarn
Trivisa's M390 crossbar-lock folder designed by Fabian Hobbelen: a 2.87 inch modified tanto with a machined fuller, inside-out patterned titanium handle, ceramic bearings, 100 g.

Fabian Hobbelen
The independent designer behind the Skarn - clean geometry, purposeful details and an inside-out scale pattern that cuts weight while adding grip.

M390 Steel
Bohler's Austrian powder-metallurgy stainless in the 20CV/204P class: first-class edge retention, near-saltwater corrosion resistance, and a taste for diamond sharpening stones.

Modified Tanto
A blade with a straight primary edge meeting an angled tip section. It puts a strong, pierce-worthy point on a blade that still slices.

Fuller
A long groove machined along the blade flat. It lightens the blade without thinning the spine and gives the eye a clean line to follow.

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.

Titanium Handle
Aerospace-grade Ti-6Al-4V scales: stronger than steel by weight, immune to corrosion, and warm-feeling in cold weather.

Satin Finish
Longitudinal grind lines on the blade bevels - brighter than stonewash, glare-cutting, and easy to clean.

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.

Rose Gold Anodizing
A heat or voltage-created oxide layer on titanium that reads warm bronze-gold. It is not paint - it will not chip or peel, though it can burnish under heavy abrasion.

PVD Coating
Physical vapour deposition: a hard, thin metallic-ceramic layer bonded to the steel. Rose-gold and black finishes resist scratches; edge wear is cosmetic, not structural.

Who Should Buy the Skarn-W

• Collectors who want M390, titanium and a designer name under $180.
• Carriers who value edge retention above all - M390 outlasts mid-range steels for weeks.
• Left-hand users - the crossbar lock and thumb stud are fully ambidextrous.
• Fans of milled titanium handles with real engineering detail.
• Anyone shopping a presentation-box gift for a serious knife person.

Who Should Skip It

• Budget buyers - M390 plus titanium commands a premium; the Koala covers the basics for far less.
• Users who sharpen on cheap aluminium-oxide stones - M390 wants diamond plates.
• Heavy prying and twisting - M390's hard fine-grained apex can chip under lateral load.
• Large-hand users who want a fat handle - the 3.7 inch titanium frame is compact.

Care & Maintenance

• Wipe the blade dry after every use; M390 is highly stainless, but the finish lasts longer when wiped clean.
• One drop of light knife oil at the pivot every two to three months, then swing the blade a dozen times so oil reaches the ceramic bearing.
• Sharpen on a diamond plate or CBN stone at 15-18 degrees per side; M390's vanadium carbides defeat ordinary aluminium-oxide stones.
• Work in light passes and finish on a loaded strop - heavy pressure on a 60+/-2 HRC edge just rounds the apex you set.
• Do not pry, twist or use the tip as a screwdriver; the fine M390 apex can chip under lateral load.
• Wipe the rose gold anodized titanium with a dry cloth; do not use abrasive polish or the anodic colour will burnish away.
• Blow lint out of the crossbar-lock channel before oiling; grit under the lock bar is the usual cause of a gritty action.
• Check the body and clip screws every few months with the correct Torx driver; vibration on a keyring or pack can back them out.
• Store the knife closed and dry, never sealed in a damp pouch against the steel.
