US Patent 11904484 Knife with specialized balance and blade length

A knife including a handle, a blade, and an enclosed blade action is configured to have an optimized weight ratio of the blade to the handle when the blade is extended, the handle can be kept relatively smaller and lighter with a slimmer profile, but without sacrificing rigidity and durability. The slimmer and lighter handle allows a longer blade but without the increased weight resulting from a bulkier handle typically necessitated by the longer blade.
