The 2051ROLBW and 2051OLBW are the same knife in every structural respect — identical D2 tool steel, identical blackwash blade finish, identical OD green anodized aluminum handle, identical DuraLock crossbar lock, and identical carry configuration. The sole difference is blade geometry. The 2051ROLBW runs a reverse tanto — a reinforced, mass-forward tip ideal for controlled puncture, strapping, and tip-heavy work. The 2051OLBW runs a spear point — a symmetrical centered tip with a longer usable belly better suited to general slicing and everyday cutting tasks. Both are the same OD green blackwash platform; the choice is purely which blade geometry matches your carry tasks.

The Mini Iridium lineup now spans seven variants, all sharing D2 steel, DuraLock crossbar lock, 3.0-inch blade, and the same carry configuration. The 2051RBLK is reverse tanto with black-coated blade on a black handle. The 2051R is reverse tanto with satin blade on a gray handle. The 2051ROLBW is reverse tanto with blackwash blade on an OD green handle. The 2051OLBW is spear point with blackwash blade on an OD green handle. The 2051BRZBW is spear point with blackwash blade on a bronze handle. The 2051 is spear point with stonewash blade on an ice blue handle. The 2051BLK is spear point with black PVD blade on a black handle. The 2051ROLBW is the reverse tanto OD green blackwash option — the field-oriented colorway with the tip-forward geometry.

A reverse tanto features a spine that curves downward to meet the edge rather than the angular clip of a traditional tanto. The geometry reinforces the tip by concentrating blade mass forward — ideal for controlled puncture, box work, strapping, prying light materials, and any task where tip strength and precision matter. The flat grind keeps the edge versatile for slicing and general utility work, so the reverse tanto does not sacrifice EDC usability in exchange for tip performance. For field and outdoor carry where tip-heavy tasks come up regularly, the reverse tanto is the more purpose-suited geometry.

Blackwash is produced by applying a stonewash texture to the blade first, then a black coating over the top. The black settles into the recesses of the stonewash texture and wears away at the high points, creating a two-tone effect that reads as dark and low-profile against the OD green handle. On D2 steel specifically, the blackwash coating serves a functional purpose beyond aesthetics: D2 is a semi-stainless tool steel that benefits from surface protection against moisture, and the black layer across the blade face adds a corrosion barrier that bare stonewash D2 does not have. The finish will show normal edge wear at the bevel with sharpening and use, which is expected.

DuraLock is Kershaw's crossbar locking system. A hardened steel crossbar passes laterally through the handle and drops into a notch in the blade tang when the blade reaches full open, locking it positively in place across a wide contact area. To close, push the crossbar from either side with your thumb — it clears the tang notch and the blade folds freely. The crossbar provides a wider, more stable lockup geometry than a standard Liner Lock and eliminates accidental lock disengagement from lateral blade pressure. The same hardware runs across all Mini Iridium variants and the full-size Iridium series.

D2 is a high-carbon, high-chromium tool steel — semi-stainless by composition but tool steel by performance. Its high carbide content gives it significantly better edge retention and wear resistance than the 8Cr13MoV common at this price tier. The trade-off is modest susceptibility to surface rust if left wet or stored in humid conditions. The blackwash coating on the 2051ROLBW provides a functional barrier on the blade face. Wipe the blade dry after moisture exposure and apply a thin coat of blade oil before extended storage to maintain the exposed steel at the sharpened bevel.

The Mini Iridium 2051ROLBW is a manual folding knife with thumb stud deployment — not assisted-opening, automatic, or OTF — which places it in the broadest legal carry category under most state laws. A 3.0-inch blade clears the carry limit in the majority of US jurisdictions, though some cities and municipalities set lower thresholds. Knifeworks cannot provide legal advice.

The Kershaw Mini Iridium 2051ROLBW is manufactured in China under Kershaw's offshore production program. Kershaw designs, engineers, and quality-controls all models from their Tualatin, Oregon headquarters, and the Mini Iridium carries the same Kershaw Lifetime Warranty as their USA-made production pieces. Buyers who prefer domestic manufacturing should consider the Bel Air series (6105), which is USA made in Tualatin, Oregon.
