  "description": "保守作業台や資材室向けの手動金切りのこ。開いた弓形フレーム、実形状の小さな歯を持つ薄い刃と取付穴、端の保持具、張力調整風のねじ・蝶形つまみ、開いた握りを造形。刃は固定され、切断物・切粉・切断動作はありません。実際の刃性能、張力や安全設計は未検証です。 ゲーム・可視化向け。製造・構造設計・3Dプリント用途は未検証。 外接寸法（X×Y×Z）0.491 × 0.031 × 0.202 m、2,528三角形。単位m・Y-up、水平中央の接地用原点、最下点Y=0。部品ごとの重複UV0と単色PBR材質を収録し、画像テクスチャ・UV2・コライダー・LOD・リグ・動作は付属しません。静的表示用でUnity/VRChat実機検証は未実施。STLはm・Y-up座標の形状のみで色・材質・UV・階層を含みません。",
  "descriptionEn": "A manual hacksaw for maintenance benches and stockrooms, with an open bowed frame, thin blade with modeled teeth and mounting holes, end holders, tension-adjuster exterior and wing grips, and open handle. The blade is fixed; workpieces, chips and cutting behavior are absent. Real blade performance, tension and safety design are unvalidated. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 0.491 × 0.031 × 0.202 m; 2,528 triangles. Metres, Y-up, horizontally centered placement origin with minimum Y=0, not an articulation or wall-mount pivot. Includes overlapping component UV0 and constant-color PBR materials, with no image textures, unique UV2, colliders, LOD, rig or runtime behavior. Static visualization only; Unity/VRChat editor and runtime tests have not been performed. STL uses metre-valued Y-up coordinates and contains geometry only, without color, materials, UVs or hierarchy.",
