{"params":{"colorway":{"type":"choice","default":"jet","label":"Colorway","describe":"curated glass-and-haft scheme from the kit palette; sets all four zone colours. jet = the shipped near-black glossy obsidian with a dull grey-brown patina, a mid-brown wooden haft and pale tan bark-fibre cord, as the references draw it; smoke = a smoky charcoal-grey glass with a paler patina, a lighter haft and near-cream cord; umber = a warm brown-black glass with a pale khaki patina, a dark grey-brown haft and tan cord. Any colour set explicitly overrides the scheme","options":["jet","smoke","umber"]},"blade":{"type":"choice","default":"pointed","label":"Blade","describe":"outline of the blade, the three common mata'a forms. pointed = the references: a pointed leaf 40 mm wide, widest a little past mid-length, with convex sides and rounded sloping shoulders; triangular = straight sides running from a sharp point to the broadest part at the base, 44 mm across two crisp shoulder corners; rounded = a broad spade with a convex, rounded cutting end and no point, 46 mm wide near the end, narrowing to sloped shoulders. The tang, the neck, the thickness and the facet pitch are the same for every form","affects":"geometry","options":["pointed","triangular","rounded"]},"length":{"type":"range","default":0.1,"label":"Length","describe":"overall length of the stone in metres, point to butt. Rebuilt, not scaled: only the blade between the point and the shoulders changes length (50 mm at 0.08, a stubby broad blade; 70 mm at the default 0.1; 100 mm at 0.13, a long slender one) and it gains or loses flake facets at a constant pitch. The blade width, the thickness, the shoulder turn and the 30 mm tang keep their sizes","affects":"geometry","min":0.08,"max":0.13,"step":0.005},"haft":{"type":"choice","default":"none","label":"Haft","describe":"whether the blade is mounted. none = the bare stone, as the references show it, lying on its flat underside; hafted = the tang set into the end of a short octagonal wooden shaft 15 mm across and 118 mm long, bound with a helical wrap of about six turns of bark-fibre cord over the first 20 mm. Hafted, the piece rests on the binding and the blade's underside near the point, with the shaft rising slightly behind; overall about 0.19 m at the default length. The blade and its shoulders are unchanged","affects":"geometry","options":["none","hafted"]},"wear":{"type":"range","default":0.4,"label":"Wear","describe":"0 freshly cut and clean, 1 centuries of weather: lichen, moss, salt bloom, faded paint and small chips; the object itself never changes. Here: 0 = a freshly knapped blade, every facet glossy black glass with clean edges; 0.4 = the shipped blade, still glossy black: about one facet in ten round the central ridge dulled to the patina colour and two or three small chips nibbled into the knife edges; 1 = about 60% of the ridge facets and most of the flat underside dulled, a quarter of the edge facets, and about a third of the blade-edge stations chipped (each 0.9-1.9 mm deep), the fresh chips staying glossy. Patina grows slowly at first and spreads outward from the ridge. Never changes the outline's extent, the tang, the length, the haft or its wood and cord","affects":"geometry","min":0,"max":1,"step":0.1},"obsidian":{"type":"color","default":"#18181b","label":"Obsidian","describe":"albedo of the volcanic glass: the whole stone, blade and tang, on the glossy material.
