Scope: hand- and machine-operated tools whose job is to cut, trim, punch or die-cut craft materials (paper, fabric/felt, vinyl, leather, foam/chipboard) — scissors & shears, craft/utility knives, rotary cutters, paper trimmers, craft punches, die-cutting/cutting-plotter machines. Excludes notions covered by the sewing-tools leaf (needles, pins, seam rippers, measuring tools) and non-cutting surfaces like bare cutting mats.

Seed: 1) equivalent of treadwear-grade-needs-a-caveat: blade material name (titanium-coated, tungsten, ceramic) looks like a spec but experts know coating/alloy claims aren't standardized across brands, so it compares within a brand's line, not across brands. 2) An allergist-type persona (here: a repetitive-strain/hand-safety-minded buyer) would notice handedness and blade-safety-feature first — whether the tool actually fits their grip and whether it exposes blade edge when not cutting — before noticing blade material at all.

Branches: tool_type → each value routes to that type's own facet set (scissors_subtype for scissors_or_shears; knife_blade_mechanism/blade_tip_shape/blade_change_method for craft_or_utility_knife; rotary_blade_size_class/requires_cutting_mat_and_ruler for rotary_cutter; trimmer_mechanism for paper_trimmer; cutting_machine_mechanism/design_input_method/compatible_materials_class for cutting_machine; punch_type/punch_actuation for craft_punch) — supported by each type's own source above.

Noise: cutting mats and acrylic rulers (accessories, not cutting tools themselves) — left out, named only as a dependency of rotary_cutter. Precise blade/mat dimensions in mm (Cricut mat sizes, rotary blade mm diameters) — single-sourced only, so left as qualitative size classes rather than a sourced numeric range, per the two-source rule. ASTM/CPSC child-product certification — no governing third-party standard found for this leaf (blunt tip is a described design feature, not a cited certification), so no standard facet added.

Corrections (2026-10-26):
- Added `blade_safety_feature` to `then_ask` for `scissors_or_shears`, `craft_or_utility_knife`, `rotary_cutter`, `paper_trimmer` — it was defined but unreachable in every branch.
- The "no governing third-party standard found" line above was wrong: added a judgement citing CPSC 16 CFR 1500.48-1500.49 (Cornell LII) and ASTM F963 via [wikipedia_toy_safety] (CPSIA makes F963 a CPSC requirement), wired into `blade_safety_feature`/`scissors_subtype` evidence.
- Reclassified `blade_tip_shape.source` from `listing` to `researched`; its own `listing_field_hint`/`backfill_note` already said the handle listing rarely states it.
- Added `buttonhole_scissors` to `scissors_subtype.values` (named in [wikipedia_scissors]'s own comparison table) plus a vocabulary entry; left the split `cold_start_question` alone since it is already at the 12-word cap.
- Added vocabulary entries for `wave_or_scalloped` and for `blade_material`'s `titanium_coated_steel`/`tungsten_steel`/`ceramic`/`nonstick_coated_steel`.
