Using your Deejo knife is easy. Just press the liner lock to open or close the blade safely. When using it, make sure to keep your fingers away from the blade's edge to avoid cuts. As for maintenance, after each use, wipe the blade with a dry cloth to remove any moisture or debris. If it gets dirty, you can clean it with a mild soap and water, then dry it thoroughly. The juniper wood handle should be kept dry. Avoid leaving the knife in wet or humid conditions for a long time, as it may damage the wood and the blade. Store it in a dry place, and you can use the belt clip to carry it around conveniently.
