{"product_id":"lyra-monochrome-sharpener","title":"Monochrome Sharpener","description":"\u003cp\u003eSoft charcoal and chunky graphite pencils need room to breathe during sharpening. This specialized sharpener accommodates barrels up to 9mm diameter, substantially wider than standard pencil openings, preventing the crushing and crumbling that ruins oversized drawing cores. The blade sits at an optimized angle that creates clean, gradual tapers rather than aggressive points, preserving maximum material while producing tips suited to sketching techniques.\u003c\/p\u003e\n\u003cp\u003eLYRA designed this specifically for their Rembrandt monochrome range, but it handles any jumbo-diameter drawing pencil with equal capability. The conical chamber collects shavings cleanly, while the precision-ground blade maintains its edge through dense charcoal, waxy graphite, and compressed carbon formulations. Compact enough to travel in your sketch kit yet substantial enough for studio use.\u003c\/p\u003e\n\u003cp\u003eWhether you're working through gesture drawings with vine charcoal pencils or building tonal studies with 6B graphite, this sharpener maintains the point you need without wasting precious material. The robust construction ensures it won't crack under the torque that thick-core pencils demand during sharpening.\u003c\/p\u003e","brand":"LYRA","offers":[{"title":"each","offer_id":47973838291173,"sku":"15887","price":3.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/6890\/5701\/files\/s15887_fe1b08e9-4da6-4402-8537-132848f0d88c.jpg?v=1769782448","url":"https:\/\/www.texasart.mom\/products\/lyra-monochrome-sharpener","provider":"Texas Art Supply","version":"1.0","type":"link"}
