{"product_id":"adjustable-iron-plane-no-4-773467","title":"Adjustable Iron Plane, No 4","description":"The No.4 Smoothing Plane is the quintessential woodworking tool, balanced perfectly for final finishing and general-purpose joinery. At 250mm (10\") long, its shorter sole is designed to follow subtle contours in timber to create a glass-like surface that often requires no further sanding. Precision-Milled Cast Iron Body - Features a heavy-duty iron casting with a precision-ground sole and sides, ensuring the tool remains flat and square for accurate, chatter-free performance. Fully Adjustable Frog - The adjustable \"frog\" allows you to set the mouth opening; closed tight for extra-fine shavings on difficult grain or opened up for rapid material removal. Micro-Adjustment Controls - Equipped with a knurled brass nut for precise depth-of-cut control and a lateral lever to ensure the blade is perfectly square to the mouth. High-Carbon Steel Blade - The 50mm (2\") wide blade is hardened and tempered to maintain a keen, razor-sharp edge through extended use on both hard and soft woods.","brand":"Adjustable","offers":[{"title":"Default Title","offer_id":51565146308891,"sku":"PN11P-CEN","price":21.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0814\/6488\/5531\/files\/PN11P.jpg?v=1781472656","url":"https:\/\/rockbottomnorthampton.co.uk\/products\/adjustable-iron-plane-no-4-773467","provider":"Rockbottom Northampton","version":"1.0","type":"link"}
