Using your Whitby Kent+ knife is easy. The finger hole on the blade allows for quick and smooth opening. For the multi - tools, just pull them out gently and use them as you would with regular screwdrivers or scissors. When using the cap lifter, place it under the bottle cap and lift up. As for safety, always keep the blade closed when not in use to avoid any accidental cuts. Don't use the blade on extremely hard materials as it may damage the edge. To maintain your knife, clean it with a dry cloth after each use, especially if it gets wet or dirty. You can also apply a little oil on the blade to prevent rust. Keep it stored in a dry place.
