Knives and Firearms
High quality knives and hunting knives need special care and maintenance. Folding and locking mechanisms of clasp knives, for example, contain many movable parts and springs. Just one drop (and no more) of lubricant is perfect to keep them working for many years. Blades of fixed-blade knives also require oil for conservation and rust prevention.
Gunsmiths and owners of firearms utilize the Precision Oiler Pen to lubricate precisely and economically lock, slide and trigger mechanisms, etc.
