Trivisa Scarab-DM JM03-DM-M Mirror Finished M390 Blade Titanium Handle Crossbar Lock Folding Knife

Meet the Trivisa Scarab-DM JM03-DM-M, a compact folding knife created by the TRIVISA Team for everyday carry and outdoor tasks. Its 2.99-inch M390 stainless-steel blade features a mirror finish and swedge profile, pairing refined appearance with excellent wear and corrosion resistance. The steel is rated at 60±2HRC for edge retention; its hardness may make sharpening more demanding. A lightweight titanium handle and crossbar lock complete the design, while ceramic ball bearings support smooth operation. Measuring 6.79 inches overall, it closes to 3.8 inches and weighs just 2.36 ounces. The 76-mm blade is 2.2-mm thick. A practical choice for hiking, camping, fishing, hunting, and daily carry, this knife combines compact dimensions and materials.

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 Scarab-DM - DLC Mirror M390 Swedge Blade in an Anodized Titanium Frame

The M390 swedge blade on the Trivisa Scarab-DM is finished in dark DLC mirror, riding on a bronze anodized titanium handle with a crossbar lock and ceramic bearings at 66.8 g (2.36 oz). More folding knives and EDC gear at EDCMALL.

M390 Swedge Blade: Powder-Steel Edge Life in a Compact Frame

Bohler M390 is the powder-metallurgy benchmark: roughly 20 percent chromium, a dense vanadium carbide field, and edge life that runs weeks past mid-range steels. On this 2.99 inch swedge blade, hardened to 60+/-2 HRC on 2.2 mm stock, it cuts packaging, cord and food for a month between touch-ups and will not spot in a sweaty pocket. The swedge bevel along the spine sharpens the tip geometry and lightens the profile, and the grey or bronze anodized titanium frame carries the whole package at just 66.8 g. The honest trade is sharpening - bring a diamond plate - and no prying with the fine tip. Compare M390 with CPM-S35VN, CPM-20CV and CPM-MagnaCut in the table below.

Why the Trivisa Scarab Belongs in Your Pocket

• 2.99 inch M390 swedge blade at 60+/-2 HRC on 2.2 mm stock.
• DLC Mirror blade finish - a hard dark diamond-like carbon layer polished smooth - scratch and glare resistant.
• Bronze Anodized Titanium with a satin-machined, anodized finish.
• Anodized thumb stud for fast, one-handed opening.
• Crossbar lock: ambidextrous, dirt-tolerant and finger-safe on closing.
• Ceramic ball bearing pivot that stays glassy for years.
• Steel pocket clip, tip-up, and a lanyard-ready rear.
• 66.8 g (2.36 oz) on a 6.79 inch frame - premium steel without pocket drag.

Best Uses for the Scarab-DM

• Daily pocket duty: mail, packaging, tags and food prep on a 2.99 inch swedge blade.
• Office and urban carry where the anodized titanium frame reads as jewellery-grade finish.
• Weekend hiking and camping where a compact, corrosion-resistant folder earns its pocket spot.
• Collection display for the M390 pedigree and the layered or polished finish.
• Precision slicing where the swedged tip geometry and fine edge excel.

Frequently Asked Questions

What steel is the Scarab blade?
M390 - hardened to 60+/-2 HRC. It offers first-class edge retention and corrosion resistance; sharpen it on diamond abrasives and keep prying loads off the fine tip.

How does the knife open and lock?
Press the anodized thumb stud and the ceramic ball bearing pivot swings the blade out one-handed; the crossbar lock wedges behind the tang from above and is fully ambidextrous and finger-safe on closing.

What is the handle made of?
Bronze Anodized Titanium - aerospace-grade scales coloured by a surface oxide layer, not paint, with a machined satin finish and a steel pocket clip.

How big is it?
6.79" (172.4 mm) open, 3.8" (96.4 mm) closed, 2.99" (76 mm) blade at 0.08" (2.2 mm), and 66.8 g (2.36 oz) - a compact titanium folder that disappears in the pocket.

Is the Damascus pattern the same on every blade?
No - on the Damascus variants the acid-etched layer pattern varies blade to blade, so the knife you receive is visually one of a kind.

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

Scarab
Trivisa's compact swedge-blade folder: a 2.99 inch blade, 6.79 inches open, anodized titanium handle, crossbar lock, ceramic bearings, 66.8 g.

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.

Swedge
A bevel ground along the blade spine. It lightens the profile, sharpens the tip's geometry and adds a distinctive 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.

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

Anodized Titanium
Titanium colour produced by heat or voltage, forming a surface oxide layer. It is not paint - it will not chip or peel.

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.

Pocket Clip
A spring steel strip that holds the folded knife at the top of your pocket, tip-up on this model.

DLC Coating
Diamond-like carbon: a hard, dark, low-friction layer bonded to the steel. It resists scratches and glare; edge wear is cosmetic, not structural.

Who Should Buy the Scarab-DM

• Buyers who want M390 performance in a sub-3-ounce titanium folder.
• Anyone who values an ambidextrous crossbar lock over flipper tactics.
• Collectors chasing the colour-coded Scarab lineup (grey, bronze, black frames).
• Wet-climate carriers who want a folder that shrugs off sweat and rain.
• Minimalists who like a clean swedge profile and a compact 3.8 inch closed length.

Who Should Skip It

• Budget-first buyers - a 14C28N folder at a third of the price cuts cardboard just as well.
• Anyone who wants a fidget-style flipper or button action; this opens on a thumb stud.
• Pry-prone users - the fine M390 tip is a slicer, not a lever.
• Users who need a heavy-duty work blade; 2.2 mm stock is built for slicing, not leverage.

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.
