Tourney shields are lighter than war shields therefore faster to block incoming blows. Can be used for longer periods of time, due to lighter weight. Smaller, therefore easier for your opponent to get around. Tend to wear out fairly quickly from constant pounding. In war situations, tend to get you killed due to smaller size.
Materials range from curved plywood, flat ply wood, plastic, or metals.
Sizes are usually measured to fit each individual fighter tastes. They too cover from eye slot to knee. Attached brace poles on the back make this shield free standing. Horned War Shield is another war shape that is popular. In common use at the Estrella war.
