Abstract
A lock-back foldable tool includes a folding locking channel which nests outside of the channel-shaped handle of the tool. The locking channel fits closely over a spring, integral with the web of the channel-shaped handle, which bears against a cam surface on the base of the tool blade. When the blade is in extended position with respect to the handle, pivoting of the blade with respect to the handle will cause deflection of the spring. When the locking channel is selectively positioned over the spring, it prevents deflection of the spring, thereby locking the blade into extended position.
