Drawing required — production is strictly to your drawing. The drawing governs length, thickness, hole pattern and edge angle; all sizes shown on this website are for reference only. No drawing? Send the old blade or photos with dimensions — we issue a drawing for your approval before any steel is cut. 下单须提供刀片图纸（PDF / DWG / 手绘均可），一切以图纸为准；无图纸请寄旧刀或提供带尺照片，我们出图经您确认后投产。
