You've all seen them - old style, bone-handled, fingernail-opening pocketknife with a pivoting handguard that folds flat against the open side of the handle, and opens with the blade into a hand guard. (AG Russell sometimes has them, Smoky Mountain has one by Puma in the March catalog). Since a lot of you 'hard-use' guys complain about handle ergos, lack of a sufficient guard, etc. wouldn't combining the swing-guard with a one-hand opening be perfect ? Someone could make a really smooth guard that blends into the handle when closed, and won't inhibit opening performance. What'dya think ?
