Overview & First Impressions
The higonokami is Japan's most iconic pocket knife: a simple skinner-ground blade chased by a levered handle. Tenable's B2135 keeps the silhouette but upgrades everything that made the original fragile, and all five variants are now in stock at EdcMall. Where the traditional brass body flexed, the B2135 uses G10 and micarta over steel liners, so the lever action has become a proper liner lock. It is a heritage pattern rebuilt for people who actually carry Tenable knives daily.
Materials & Construction
Four of the five variants run D2 steel, an air hardening tool steel with high carbide density that holds a working edge through cardboard, rope and packaging tape far longer than the blue paper steel of the original. The A3 swaps in a water ripple Damascus blade with a twill carbon fiber handle for collectors. D2 trades some rust resistance for wear life, so ten seconds of drying after wet work keeps it flawless for years.
Design & Details
The nagging question with any higonokami homage is the handle: traditional examples offer no guard and no lock. Tenable solved it with a choil and a small finger swale on the G10, so forward grip pressure lands on texture instead of an edge. The A4's jade G10 is the standout finish, translucent at the edges under sunlight. Grind is a shallow hollow that bites paper cleanly. This is one of the few folding knives that reads both vintage and modern at once.
Real-World Use
Carry behavior is the point of the exercise. The slim spine and lever silhouette disappear in a jeans watch pocket, yet the locked blade does everything a tradition friction folder never could: push cuts, light prying with the spine, food prep at a picnic. Open one handed with a wrist flick on the lever, close with the thumb stud. As EDC knives with a story go, few at this price deliver it this cleanly.
Ownership Notes
Maintenance mirrors any D2 blade: wipe after acidic food, oil the pivot monthly, and let the stonewash hide the micro scratches that polished finishes collect. EdcMall recommends the A4 for first buyers because the jade handle photographs far better than the price suggests, and the A2 rose gold coated blade is the sleeper pick for collectors who want color without timascus money.
Who Is This For?
Buy this if you love Japanese knife culture but refuse to carry an unlocked blade to work, or if you want a gift that explains itself. It also fills the nostalgia slot in a rotation without giving up the safety that a modern folder demands. Left-handers should note the clip is right side only.
Final Verdict
The B2135 is a respectful translation, not a costume. Tenable kept the soul of the higonokami and bolted on the two things a modern carrier needs: a lock and a manageable steel. Pick the A4 if you want the showpiece, the A1 purple micarta if you want the workhorse. Either way you carry a conversation starter that still cuts.
