OLFA blades are extremely sharp. Handle with care. Wear safety goggles. Always be alert and attentive when using a cutter or knife. Take the time to fully learn the correct use and limitations of any cutter. Never assume that you know how to properly use a knife. Store knives and blades in a safe place. Keep out of reach of children !
A combination of Keyhole Saw and the 12,5mm MT-1 is all needed. Grab one CS-5 instead of carrying 2 tools for one workday. Snap-off blade cutter is placed in the deep part of the body to avoid unexpected touching while using the saw on the other side. Saw makes a hole in a dry wall and cut wood, while cutter exposes hard wiring and cut cardboard. One necessity for electricians : the saw blade is bi-directional, works as a pull-saw as well as a puch-saw. Sharp-pointed tip drills a hole in a board to start cutting. The hard-to-bend 12,5mm-wide x 0,45mm-thick snapp-off blade cuts through materials stronger than people expect from its compact appearance.
