The 8″ Snap-In is a hybrid improvement of the R-Squared & the small & medium versions of our hand tools. They allow for delicate work without having to worry about applying too much pressure & breaking the tool. The 8″ Snap-In features the replaceable reversible blade insert design. Changing blades is done without tools by firmly “snapping” the blade out & back in. The addition of a finger rest adds increased pressure control. Designed to cut hardwood, softwood, masonite & manmade panels.
