This roughing file has a serrated (toothed) blade that abrades the leather more aggressively, creating a more textured surface — which is particularly effective when you need a strong adhesive bond on smooth or firm vegetable-tanned leather.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003ch3\u003eWhich blade width should I use for wallet panel assembly?\u003c\/h3\u003e\n\u003cp\u003eFor laminating wallet panels (flesh side to flesh side), the 5mm or 10mm blade covers broad surfaces efficiently.
