Trivisa Skarn-M JM11-M-M Mirror Finish 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-M - Mirror Finish M390 Modified Tanto in Milled Titanium

Designer Fabian Hobbelen's Trivisa Skarn-M: a mirror polished M390 modified tanto with a machined fuller, an inside-out scale pattern milled titanium handle, a crossbar lock and ceramic bearings at 100 g (3.52 oz). More folding knives at EDCMALL.

M390, a Fuller, and a Handle Pattern You Feel Every Pickup

The Skarn is named for a metamorphic rock formed under pressure, and the design logic shows: Fabian Hobbelen's inside-out scale pattern is milled deep into the titanium so it lightens the handle, adds grip, and reads like layered stone under light. The 2.87 inch M390 modified tanto is polished to a true mirror, grooved with a stylish fuller, and hardened to 60+/-2 HRC - powder-steel edge life with a strong, pierce-worthy tip. The crossbar lock and ceramic bearings finish a knife that is refined, precise, and made to be used. Compare M390 with CPM-S35VN, CPM-20CV and MagnaCut in the table below.

Frequently Asked Questions

Who designed the Skarn?
Dutch designer Fabian Hobbelen, known for clean geometry and purposeful details. The inside-out scale pattern is his signature texture on this model.

What steel is the blade?
Bohler M390 powder-metallurgy stainless at 60+/-2 HRC with a mirror polish and a machined fuller. First-class edge retention; sharpen on diamond and keep pry loads off the tip.

What is the handle pattern?
A milled inside-out scale pattern cut into the titanium: it reduces weight, adds grip and gives the handle a geological, layered look you feel on every pickup.

How does it open and lock?
The thumb stud swings the blade out on ceramic ball bearings; the crossbar lock wedges behind the tang from above and releases with a pull of the bar.

How big is it?
6.57" (166.6 mm) open, 3.7" (93.6 mm) closed, 2.87" (73 mm) blade at 0.14" (3.5 mm), and 100 g (3.52 oz).

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 titanium-frame folders around premium steels with a clean in-house design language.

Skarn
Named for a metamorphic rock formed under pressure: a signature Trivisa design by Fabian Hobbelen with an inside-out scale pattern milled into the handle.

Fabian Hobbelen
The Dutch designer behind the Skarn's clean geometry - purposeful details, everyday-carry balance and a handle texture you feel every pickup.

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.

Mirror Finish
A fully polished blade surface that reflects like glass. Stunning under light, but it shows every micro-scratch - wipe it clean and store it dry.

Inside-Out Scale Pattern
The Skarn's milled handle relief: it reduces weight, adds grip and gives the titanium a layered, geological look.

Who Should Buy the Skarn-M

• Collectors who want M390, mirror polish and designer provenance in one piece.
• Fans of Fabian Hobbelen's clean, geometric design language.
• Users who appreciate milled titanium over flat slabs.
• Buyers who want a tanto profile on a premium steel rather than a budget blade.
• Anyone shopping a signature Trivisa piece as a gift.

Who Should Skip It

• Users who fear micro-scratches - a mirror finish shows every mark.
• Budget-first buyers; M390 and milled titanium put this in premium territory.
• Anyone who wants a slicer-heavy profile; the tanto geometry favours the tip.
• People who want light carry at all costs - 100 g plus titanium hardware.

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 anodized titanium scales with a dry microfibre cloth; the colour is a surface oxide, so keep solvents off it.
• 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.
