Usage recommendations

Keep blades dry and store the pack in a safe place away from children. Use appropriate cutting mats and protect hands with gloves if needed for extended or repetitive cutting. For thicker or tougher materials, choose a blade or tool designed for heavier-duty cutting to avoid premature wear.
