Overview & First Impressions
Tenable's Orion platform pairs a slicey 14C28N blade with patterned G-mascus laminate handles, and the two most popular expressions of that formula are the B1089A1, stonewashed blade over black and red G-mascus, and the B1089A7, blackwashed blade over multicolor topo-print scales. Mechanically the knives are twins: same liner lock, same profile, same edge. What separates them is finish philosophy and how each ages in a pocket, which is exactly the kind of decision worth thirty seconds of thought before buying into Tenable knives.
Build Quality & Materials
Both Orions run the same Sandvik 14C28N stainless, chosen for its exceptional sharpening response, fine edge quality, and solid corrosion resistance at a friendly price. The A1's stonewash finish is raw steel mottled by tumbling media, which scatters light and conceals the fine scratches of daily use naturally. The A7's blackwash adds a coating over that same treatment, further muting reflections and adding a thin sacrificial layer over the edge shoulders. G-mascus handles, laminated G10 in layered patterns, provide grip and moisture immunity on both, with the multicolor topo print of the A7 being the more visually loud of the pair.
Design & Craftsmanship
The Orion's liner lock sits on stainless liners with smooth washers and a thumb-stud opening action tuned light and fast. The handle's G-mascus lamination gives each knife a subtly unique pattern, since the layered print shifts piece to piece, making every Orion slightly individual. Blade geometry is a full flat ground drop point with a long belly, optimized for slicing rather than prying. Both variants carry deep and ride slim, and both feel more expensive in hand than their price suggests, a signature of current Tenable knives design among contemporary folding knives.
Performance & Real-World Use
Functionally, the choice is about environment and temperament. The A1's raw stonewash suits users who sharpen often and want to read the steel's condition at a glance, and it looks increasingly seasoned rather than worn over time. The A7's blackwash suits low-light work and anyone who prefers their knife to look the same in year three as on day one. Cutting performance is identical: boxes, cord, fruit, and camp chores all fall quickly to the fine 14C28N edge, which recovers sharpness in under a minute on a basic stone.
Carry & Pairing Notes
A few ownership notes apply to whichever Orion you pick. Both share the same liner lock, washers, and 14C28N edge, so one care routine covers the pair: a monthly pivot oil, a strop between touch-ups, and a rinse when the action picks up grit. G-mascus handles hide wear completely, and the layered patterns mean your knife is subtly unique even next to its sibling. Stonewash shows the steel's honest state; blackwash keeps its secrets. Either Orion punches well above its price among everyday EDC knives, which is exactly why Tenable keeps selling out.
Who Is This For?
Pick the A1 if you love honest steel and classic red-black styling; pick the A7 if stealth and statement patterns appeal in equal measure. Collectors of G-mascus handles will eventually want both, since the prints differ even between matching variants.
Final Verdict
One platform, two personalities: raw stonewash warmth versus blackwashed stealth, both riding on Tenable's excellent 14C28N slicer. Either Orion delivers premium feel at value money. Choose your finish and order at EdcMall.
