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.

Frequently Asked Questions

What is B-Lock?

B-Lock is Bestechman's crossbar-style lock: a spring-loaded bar spans the handle and wedges behind the blade tang for strong, ambidextrous lockup.

How hard is M390 to sharpen?

M390 requires diamond or ceramic abrasives, but it also stays sharp much longer than budget stainless steels.

Is the Sprite legal to carry everywhere?

Check your local blade-length laws. The 2.36-inch blade is compact, but regulations vary by city and state.

Which handle is lightest?

The G10 variants weigh 1.59 oz; the titanium and crystallized titanium variants weigh 2.12 oz.

Glossary of Key Terms

M390
A Bohler-Uddeholm powder-metallurgy stainless steel at 59-61 HRC, packed with hard vanadium and chromium carbides. It holds an edge near the top of production knife steels and resists corrosion exceptionally well.

Crossbar Lock
A spring-loaded bar spanning the handle that wedges against the blade tang - fully ambidextrous and among the strongest folder locks.

Ceramic Ball Bearing
Pivot bearings made of ceramic that stay glassy smooth, resist corrosion and keep a flipper action consistent in humid pockets.

Crystallized Titanium
A titanium surface treatment that grows a frost-like crystalline pattern; no two handles finish exactly the same.

Deep Carry Clip
A low-ride pocket clip that sinks most of the handle below the pocket rim so only a sliver shows.

HRC
Rockwell Hardness C scale: the industry standard for reporting blade hardness. Higher numbers mean harder, more wear-resistant steel.

Bestechman Sprite - Who Should Buy / Who Should Skip

Who Should Buy

• Users who want super-steel edge retention in a compact, pocket-friendly folder.
• Collectors who value limited handle finishes like flamed or crystallized titanium.
• Left-handed carriers who need an ambidextrous lock and clip.
• Anyone who wants a crossbar lock in a smaller-than-average EDC footprint.
• People who prefer low-maintenance corrosion-resistant steel.

Who Should Skip

• Users on a tight budget; M390 and titanium carry a price premium.
• Those who want a large hard-use chopper - this is a compact EDC blade.
• People who do not own diamond sharpening gear and refuse to learn stropping.
• If your local laws limit blade length, verify the 2.36-inch blade is compliant.

Bestechman Sprite - Care & Maintenance

1. Wipe the blade dry after every use - moisture left at the pivot migrates into the lock face overnight.
2. Add one drop of quality knife oil to the pivot and lock contact points monthly, then work the action to spread it.
3. Blow pocket lint out of the handle with compressed air before oiling so grit never grinds inside the pivot.
4. Wash with warm water and mild dish soap when it gets grimy, then dry completely before it goes back in the pocket.
5. Touch the edge up on a 1000/3000 grit stone system; stropping on leather keeps a working edge alive for weeks.
6. Never put the knife in the dishwasher - heat and detergent wreck handles, bearings and edge geometry.
7. Do not pry, twist or use the tip as a screwdriver; even 60 HRC steel chips under hard lateral load.
8. Store it dry with a vapor tab; for long-term storage, coat the blade with a light film of mineral oil.
9. Re-tighten pocket clip and body screws periodically with the correct Torx driver, not a worn flathead.
