Midwest Snips forged blade offset model aviation snips are the world's best! These models perform superior to respective model ASME Performance Requirements. Our offset model aviation snips are "The Sheetmetal Tradesman's Choice" because they are truly the easiest models to use in a variety of sheetmetal cutting applications. The offset blade pattern flows material away from the blades. This allows the snip to move forward without interference when making cuts through long sheets. It also allows the snip to cut tighter curves than other blade pattern models. Cuts straight and wide curves to the left and right. Use in either hand. Bottom blade serrated. Slightly longer blade cut length than left and right models.
