Overview & First Impressions
Drystone walling is all gloves, grit and cold hands. You spend the day picking stone, setting a through-stone and trimming a cope, and the knife in your pocket opens cement bags, cuts twine and marks a line on a batten. The Tenable Riflestock B2131S4 is built like a gunstock and carries like a pen, which is the combination a waller actually wants when the toolbelt is already heavy.
Materials & Construction
Nitro-V is a nitrogen-bearing martensitic stainless with a fine carbide structure, and the grey TiCN coating on this blade adds a hard, low-friction surface on top. Tenable knives chose it for edge stability rather than maximum wear resistance, which is correct for a knife that cuts rope, twine and bagged sand rather than cardboard all day. It touches up quickly at the end of a shift when your hands are cold and tired.
Design & Details
The lock back is the reason this knife suits a waller. There is no detent to fill with grit and no flipper tab to snag on a glove; you open it with a thumb nick, it locks with a positive click and it stays locked. The olive G10 handle is textured enough to hold with wet gloves, and the gunstock profile tapers so the knife sits low in a pocket without printing.
Real-World Use
A walling day involves cutting baling twine, opening bags of type-1 aggregate, trimming the tape on a bundle of shims and scoring a line on a timber batten. Among EDC knives sold for outdoor work, the Riflestock is refreshing because it is slim and quiet rather than oversized. The TiCN finish shrugs off the abrasive dust that gets into every seam, and a rinse at the end of the day is enough.
Ownership Notes
Rinse the blade and blow grit out of the lock recess before you oil anything, because oil plus stone dust makes a grinding paste. Dry the knife closed and store it in a pouch, not a pocket full of sand. Touch up the edge with a few passes on a fine diamond rod at the original angle, and never lever a stone with the tip, which is the fastest way to break a fine point. Most folding knives carried on site end up full of grit within a week. This one does not, because the lock back has almost no cavity to fill, which is the quiet reason wallers keep buying the same pattern year after year instead of chasing a flipper.
Who Is This For?
This is the knife for the waller, the landscaper, the fencer and anyone who works outdoors in gloves. It also suits the office carrier who wants a slim lock back that does not look aggressive. Skip it if you want one-handed flipper deployment. EdcMall stocks the Riflestock in several handle and coating combinations.
Final Verdict
The B2131S4 is a mature design: a Nitro-V blade under TiCN, a lock back that ignores grit, and a gunstock handle that carries like a pen. It will never be the knife you show people, and it will be the one you reach for every morning. Buy it, rinse it, and keep it out of the sand.
