About the Product
The Chris Reeve Knives Large Sebenza 31 is a premium folding knife built for long-term reliability, not flash. You get a stonewashed CPM S45VN stainless blade and a titanium handle with the company’s Reeve Integral Lock (frame lock) updated with a ceramic ball interface for wear resistance. In testing and long-term owner reviews, the Sebenza’s action stays smooth and the lock remains secure even after repeated maintenance—helped by CRK’s precise tolerances and straightforward construction. It’s not the fastest opener (thumb stud, no flipper), and the standard clip isn’t deep-carry, but the trade-off is a design that’s durable, serviceable, and predictable in everyday use. Compared with many high-end flippers on bearings, the Sebenza favors longevity and easy upkeep over speed.
Ownership is supported by a lifetime defect warranty, plus factory clean/tune/sharpen service. The process is clear and online, though you’ll typically cover return shipping and the warranty is for the original configuration/owner with exclusions for wear or mods. Replacement parts and accessories are available, and CRK publishes FAQs and size/spec pages that make it simple to maintain a knife intended to last for years.
About Chris Reeve Knives
Chris Reeve Knives (CRK) is a Boise, Idaho–based maker that has quietly become synonymous with durability, precision, and long-term serviceability. Founded in 1984 by South African-born knifemaker Chris Reeve, the company developed pioneering features like the Reeve Integral Lock and has partnered with Crucible to help develop premium steels (CPM S30V, S35VN, S45VN) tailored for edge retention and toughness.
CRK emphasizes longevity not just through design but through support. Their lifetime defect warranty ensures failures from workmanship or materials are remedied free of charge, provided the knife remains in original configuration. They also offer complimentary factory sharpening, repair services, and publish detailed maintenance guides—an ecosystem built for owners who want a knife that can last decades.
Over the years, CRK has earned strong trust in the knife community. Long-term user accounts highlight that CRK knives maintain “faultless” operation across many years of real-world use. The brand remains family-owned (Anne Reeve and son Tim oversee operations) and produces in smaller batches, which ensures quality control but sometimes leads to extended lead times.

(W 25%)
PRO
S45VN is a high-end stainless steel with good corrosion resistance for real-world use.Independent long-term user reports over years show little to no staining or corrosion even after tough use.
CON
No coating or proprietary rust-proofing beyond standard steel choice is advertised.Some criticisms exist that steel choice (when CRK used S35VN) was not always optimal vs premium alternatives.

Durability of the locking mechanism under repeated stress.
Ideal: Reliable lock design (e.g., frame or back lock) tested for thousands of open/close cycles without failure.
Confidence —
MEDIUM

(W 25%)
PRO
Uses the Reeve Integral Lock (a robust frame/lockbar design) with improved interface (ceramic ball) for longer wear.Long-term reviews report no lock failures in years of heavy use.
CON
Some community reports of very slight “rock” or drift over extensive use, though usually not functionally problematic.

70.0%
(W 15%)
PRO
CRK uses precise tolerances and quality parts to reduce wear; reviewers note the action remains smooth after repeated disassembly and reassembly.The new version uses a hardened bearing / ultrahard interface at the lockbar-blade interface, reducing wear on the lock.
CON
No published lab endurance test data on pivot lifespan over hundreds of thousands of cycles.Maintenance (cleaning, lubrication) is essential to prevent wear; neglect may degrade performance.

(W 40%)
PRO
CRK specifies sharpening at 18°-20°, a standard angle compatible with common sharpening systems.Owners report that even after hard use, blades can be refreshed via common sharpening stones or systems without exotic tools.
CON
Tough steels like S45VN may demand more skill and finer abrasives to achieve optimal edge compared to softer steels.Some newer steel variants (e.g., Magnacut) may challenge typical sharpening routines (though not standard for all 31s).

PRO
CRK lists a parts store (CRK Parts) indicating availability of replacement screws, clips, and hardware.Third-party / authorized third-party parts are explicitly recognized and may not void warranty.
CON
Consumable parts (screws, washers) are excluded from warranty unless failure due to defect—implying user may need to purchase parts.Rare or variant parts (e.g. inlays, custom finishes) may have limited availability or longer lead times.

Serviceability
Whether the knife can be disassembled and reassembled without damage.
Ideal: Standard screw fasteners and clear design allowing easy maintenance.
Confidence —
MEDIUM
4 sources
85.0%
(W 30%)
PRO
Numerous long-term reviews note that users repeatedly disassemble and reassemble the Sebenza without dimensional drift or loosening.CRK’s design uses standard fasteners and accessible layout, making maintenance feasible by owners.
CON
Requires careful alignment and torque control; improper service may harm lock or tolerances.Modifications render warranties void, limiting what users can safely do.

(W 35%)
PRO
S45VN (used in newer 31s) is designed to improve edge retention over S35VN.User reports over years of everyday use show minimal edge degradation under moderate tasks.
CON
Under heavy or abusive use, edge may dull and require resharpening like any high-performance steel.Earlier iterations with S35VN had critics noting that retention was good but not stellar versus newer steels.

Ideal: Handle designed for secure, comfortable grip with minimal fatigue or hot spots.
Confidence —
MEDIUM
3 sources
85.0%
(W 25%)
PRO
Long-term reviews praise the handle shape, grip, and contours as comfortable over extended use.Ti handle with stone-blasted or milled texture provides initial grip; over time gives pleasant wear.
CON
Some users find the clip’s new angled position slightly less ideal for deep carry.Edge ergonomics may require a “break-in” period to fully smooth the action.

Ideal: Multiple carry positions with durable pocket clip or reliable sheath.
Confidence —
MEDIUM
3 sources
70.0%
(W 20%)
PRO
Comes with a titanium pocket clip; good retention and clean fit.Slim profile and crowned spine help reduce pocket interference and make carry comfortable.
CON
Clip is not deep-carry, so the knife rides relatively high in pocket.Limited carry positions: only standard tip-up clip is offered, no sheath options in typical configuration.

Blade Deployment
Ease and reliability of opening mechanism.
Ideal: Smooth, consistent deployment via thumb stud, flipper, or assisted mechanism.
Confidence —
MEDIUM
3 sources
75.0%
(W 20%)
PRO
Deployment via thumb stud is smooth, precise, and reliable, as highlighted by multiple reviews.No over-engineered mechanisms — simple, robust action that is less prone to failure.
CON
Not as rapid as flipper or assisted mechanisms favored by some users.Requires manual push on stud; not ambidextrous beyond rotating clip or reorienting hand.
