QSP Orca QS179-A2 - Black Coated 10Cr15MoV Clip Point with Black G10

The QSP Orca QS179-A2 takes the same Black G10 platform and adds a black coated blade for a non-reflective, low-glance finish. The coating hides fingerprints and reduces reflection in bright conditions, while the 10Cr15MoV core still delivers VG-10-class edge holding.

At 91 g with a 3.23 in clip point, the A2 is the stealth sibling of the Orca line. The button liner lock runs on ceramic ball bearings for a fast, consistent open, and the reversible clip lets you carry it left or right.

10Cr15MoV Blade Steel - VG-10 Performance at a Working Price

10Cr15MoV is a high-carbon Chinese stainless that sits in the same family as VG-10: roughly 1.0% carbon with chromium for corrosion resistance, plus molybdenum and vanadium for wear resistance and grain refinement. In practice it delivers noticeably better edge holding than 8Cr13MoV-class steel while staying affordable enough to actually use.

• Edge retention: good to very good. Best treated like VG-10: a 20-degree-per-side edge on a medium stone holds up well for utility work.
• Corrosion resistance: very good. No special care needed beyond wiping the blade dry after wet or food use.
• Toughness: good at 59-61 HRC, but it is a high-carbon steel - avoid prying and batoning, and expect micro-chipping if you lever the edge.
• Sharpening: moderate. It is not as forgiving as 14C28N, but a diamond or ceramic stone brings it back quickly; do not let it go fully dull.
• Closest alternative: VG-10, which behaves almost identically. If you want maximum corrosion resistance instead of edge holding, 14C28N is the swap.

• Black G10 scales that stay stable and grippy when wet
• Button liner lock on ceramic ball bearings - release without putting a thumb in the blade path
• Reversible stainless steel pocket clip for left- or right-handed carry
• 7.52 in (191 mm) open, 4.29 in (109 mm) closed
• VG-10-class edge holding at a working price point
• Ceramic ball bearings for a quick, consistent one-handed open
• Slim enough for gym shorts, substantial enough for real cutting

Where the QSP Orca QS179 Performs

• Everyday carry: 91 g with a 3.23 in blade - light enough to forget, substantial enough to use properly.
• Camping and hiking: the clip point pierces packaging and tent grommets cleanly, and 10Cr15MoV holds an edge through a weekend of cordage and food prep.
• Workshop and warehouse: cutting strapping, opening cartons and trimming material where a fast, one-handed button release matters.
• Kitchen and food prep: the thin clip point and VG-10-class steel handle board work better than a thick tactical blade.
• Glove-friendly use: the button liner lock can be released without putting a thumb in the blade path, which is exactly what you want with cold or wet hands.

QSP Orca QS179 - FAQ

What steel is the blade, and how hard is it?
10Cr15MoV stainless at 59-61 HRC. QSP notes that coated blades typically read about 1-2 HRC lower at the surface than uncoated ones.

What is the handle material?
Black G10: a high-pressure fiberglass/epoxy laminate that stays dimensionally stable when wet and provides a secure, non-abrasive grip.

What lock type does it use?
A button liner lock running on ceramic ball bearings. The button releases the liner without putting your thumb in the blade path.

Does it have a reversible pocket clip?
Yes - a reversible stainless steel clip for left- or right-handed carry.

How big and how heavy is it?
7.52 in (191 mm) open, 4.29 in (109 mm) closed, 91 g (3.21 oz). That is light for a full three-inch-plus blade.

Steel Comparison: How It Stacks Up

Ratings are relative within this class of steel, not absolute. Hardness varies by maker and heat-treat protocol.

Glossary of Terms

10Cr15MoV
A high-carbon stainless knife steel with roughly 1.0% carbon, 15% chromium, plus molybdenum and vanadium. Directly comparable to VG-10 in composition and behaviour.

Button Liner Lock
A liner lock actuated by a button through the handle scale. It keeps the thin profile and strength of a liner lock while letting the blade be released without putting a thumb in the blade path.

Clip Point
A blade profile with a swedged, concave spine running to a fine point. It pierces cleanly and keeps a long straight edge, at the cost of a slightly weaker tip than a drop point.

Ceramic Ball Bearing Pivot
A pivot running on ceramic balls instead of phosphor-bronze washers. Lower friction, smoother opening, and almost no break-in period.

HRC
Rockwell C hardness. QSP runs 10Cr15MoV at 59-61 HRC; coated blades may read about 1-2 HRC lower at the surface than uncoated ones.

Black G10
A high-pressure fiberglass/epoxy laminate in black. It stays dimensionally stable when wet and gives a secure, non-abrasive grip.

Who Should Buy the QSP Orca QS179 - and Who Should Skip It

Who should buy it

• Buyers who want VG-10-class edge holding at a fraction of the price
• Anyone who wants a fast one-handed button release rather than a thumb stud
• Daily carriers who want a genuinely light 91 g folder with a full 3.23 in blade
• Users with gloves on for part of the day - the button liner lock is easy to work with cold, wet or gloved hands
• Riders and commuters who want a non-reflective coated blade

Who should skip it

• Buyers who need extreme toughness - 10Cr15MoV at 59-61 HRC is a cutting steel, not a prying tool
• Anyone who will not maintain an edge: this steel needs scheduled touch-ups, unlike 14C28N
• Left-handed users who need a fully ambidextrous lock; the clip reverses but the button does not move
• Users who want a heavy, oversized folder - the Orca is deliberately slim
• Collectors looking for titanium or carbon fiber everything - the Orca is a working knife

Care & Maintenance

1. Wipe the blade dry after food, salt water or fruit juice. 10Cr15MoV is stainless, but citrus and salt will still mark it if left on.
2. Touch the edge up on a ceramic rod or medium stone every few weeks rather than waiting for it to go fully dull - this steel rewards scheduled maintenance.
3. Keep the pivot clear of grit. Flush it with a light oil and work the blade through its arc to distribute it.
4. Put one small drop of knife oil on the ceramic bearings and the detent track occasionally. A drop, not a flood.
5. Do not pry, twist or baton with a folding knife. 10Cr15MoV at 59-61 HRC can micro-chip under impact loads, and the button lock is not a crowbar.
6. Re-tighten the body and clip screws occasionally - vibration loosens hardware even with thread locker from the factory.
7. Store the knife fully closed in a dry place, not half-open where the lock and detent sit under load.
8. If blade play develops, adjust the pivot in small increments. Over-tightening costs you the smooth bearing action you paid for.
9. Wash Black G10 scales with warm soapy water and a soft brush; the material is impervious to moisture and most solvents.
10. Keep abrasives away from the coated blade. Clean with an oiled cloth, not a scouring pad - you will strip the coating before you polish the steel.
