Lansky Tri-Stone Benchstone review

This research-based assessment covers the exact Lansky Tri-Stone Benchstone, SKU BSTR100. Its manufacturer identifies 200-grit diamond, 280-grit alumina oxide and 1,000-grit ceramic surfaces in one plastic base, plus manual full-edge instructions. It is distinct from Lansky clamp kits and the pivoting Work Sharp Benchstone. I have not used or tested it; this reading relies on its own manufacturer record. Lansky's exact BSTR100 page is the primary source.

Three surfaces with different jobs

The three surfaces have different maker-assigned roles. The continuous 200-grit diamond is for serious repair or re-profiling a very dull or damaged edge, not an every-session starting point. The 280-grit alumina-oxide stone is the maintenance surface for an undamaged, slightly dull edge. Fine 1,000-grit ceramic is for honing and finishing. These roles are not comparative test results or promises of speed on a particular steel.

For an undamaged knife, Lansky suggests beginning on the medium surface and moving finer if needed; the coarser diamond is reserved for substantial repair. The shared base packages the stages together, but the page does not prescribe a sequence for every steel, bevel or sharpening goal.

What the hand-guided routine asks of you

Set the base flat with the chosen stone facing up. Lansky asks the user to observe the existing bevel, match it, and push the blade across the stone in one light stroke while holding a consistent angle. Its basic directions use several strokes per side; further suggestions reduce the count on later passes before moving finer. This is a user-guided routine, not an angle-clamped system.

The record gives no numeric degree mark, adjustment interval or angle convention. If a documented 20° or 22.5° setting is essential, BSTR100 does not verify it. Nor does Lansky give a blade-length or clearance chart, so the listed stone size is not an individual-knife fit guarantee.

Kitchen use is named; other tasks need separate evidence

The maker's use list names regular, filet, kitchen-blade and woodworking/chisel work. Kitchen blades are therefore a supported comparison, but the list is not a guarantee for every chef's knife or geometry. The page says the ceramic can turn a micro-serrated edge smooth; it gives no scallop-by-scallop serration method, so this is not evidence of dedicated serration support.

Woodworking chisels are named, but scissors and pocket/hunting knives are not. The source supplies no procedure for those tasks. That is a limit on what can be verified here, not proof the stones could never contact another blade.

Dry sharpening, then different cleaning for each surface

Sharpening and cleaning directions differ. Lansky says no lubrication while sharpening on any surface and specifically warns against oil on the diamond. After use, wipe the diamond with a damp rag, clean alumina oxide with Nathan's Honing Oil, and clean ceramic with a Lansky Eraser Block. The oil is a post-use cleaning instruction for the medium stone, not a sharpening lubricant. The page names the oil and block for care but does not verify either is included in a seller's package.

Bench setup and comparisons

All three surfaces are listed as 2 × 6 inches. The plastic base has non-slip rubber feet and screw holes for optional bench mounting. Lansky does not give the base's overall footprint or working clearance; measure the available spot rather than infer base size from the stone dimensions. The directions call for a flat, stable support but do not require permanent mounting.

The Work Sharp Benchstone has a pivoting abrasive assembly and documented guide positions; BSTR100 instead asks the user to follow the existing bevel across three Lansky surfaces. For a clamp-guided format, the Deluxe 5-Stone System is a separate product with a knife clamp and rod-mounted hones. Their controls and package contents do not transfer to BSTR100.

Checks before choosing this exact package

Confirm SKU BSTR100 and the three-surface/base configuration; an image alone cannot verify a seller's bundle. The page does not state whether a leather strop is included, so do not assume one. If you need a numeric angle, serration method, scissors support, named pocket/hunting use or blade-clearance limit, seek exact evidence rather than treating an unreported feature as compatible.

BSTR100 suits a shopper seeking a manual repair/maintenance/finish progression, an explicitly named kitchen-blade use, and hand-controlled angle work. Its key tradeoffs are no numeric guide or clearance limit and different care for each surface. This is a reading of the U.S. product record, not a performance, price or availability report.
