This is the Browning 323-62B replacement blades pack. Using GIN5 surgical steel, these blades have a cut better than most - they are incredibly sharp and must be treated with respect - please keep away from children.
These fit models 651 and the 652 Mirage knives from Browning - knives with interchangeable blade options.
Small, sharp, fun and reliable - trust in Browning and always keep a set handy.
