The prompt
Design a hand-held slicing tool for cutting bakery buns, consisting of a handle, a finger guard, and a mounting section for a removable blade blank. OVERALL DIMENSIONS - Total length (handle to blade tip): 220mm - Blade section thickness: 2.5mm maximum (must clear a 4mm guide slot with clearance) - Blade section width (depth, top to bottom): 20mm - Blade cutting edge length: 180mm HANDLE - Offset pistol-grip style, in-line with the blade's cutting axis (not perpendicular like a kitchen knife) - Length: 90mm, width: 30mm, height: 45mm - Rounded profile, food-safe plastic or rubber-overmolded, no sharp edges - Ergonomic contour for a full-hand grip during a horizontal draw stroke FINGER GUARD - Positioned between the handle and the blade mounting section - Rectangular flange, 20mm tall x 20mm wide x 6mm thick - Must protrude above and below the blade line so it physically cannot pass through a 4mm-tall external guide slot — this is a hard stop that registers the tool's entry position and blocks the hand from reaching the slot opening BLADE MOUNT - Flat mounting plate, 60mm long x 20mm wide x 3mm thick, extending from the finger guard toward the blade tip - Three countersunk screw holes (M4), evenly spaced along the centerline, for bolting on a separate serrated blade blank (blade blank is purchased separately, not modeled — just provide the mounting holes and a flat seating surface matching a 1.5mm blade thickness) - Blade must be removable/replaceable without disassembling the handle MATERIAL - Handle and finger guard: food-grade stainless steel or food-grade polypropylene/HDPE - Blade mount plate: food-grade stainless steel (rigid, low flex under lateral cutting force) FUNCTION - The tool is drawn by hand through a fixed horizontal slot in a cutting jig, slicing a bun sideways; travel is limited by a mechanical stop in the jig, not by the tool itself - No moving parts on the tool — it is a rigid, single-piece handle and guard assembly with a bolt-on blade
