The Inert series belongs to the Schrade Delta Class. Don’t let their slenderness fool you, the Inerts stand up to any task. This great EDC knife features AUS-10 steel with a satin finish that lends well to its EDC nature. The aluminum handles have a crisp blue color that really pairs well with the blade. With Ultra Glide technology, and a liner locking system the Inert deploys smoothly and locks up firmly. The Inert comes with a Wharncliffe blade and opens like a dream.
