12 Inches...
A standard pocket knife or folding knife no longer than 4.5 inches in the closed position is legal to carry. I believe daggers, bowie, spring loaded or butterfly knives are not legal to carry.
In York, PA, the legal length of the blade of a pocket knife is limited to 3 inches. Any blade longer than 3 inches may be considered illegal to carry in public places.

4 inches
In Pennsylvania, the legal size limit for a pocket knife is under 4 inches in length when in the open position. Knives larger than 4 inches may be considered illegal if carried for purposes beyond work, education, hunting, or other lawful activities.
Any fixed blade knife is legal. The law for a folding "pocket knife" no blade longer than 3" can be concealed. Therefore it is legal to own any knife although you can not conceal (hide on your person) any non-fixed blade over 3".
