Because they"re precision injection molded out of heavy-grade polypropylene, these bats just can"t be broken. There"s no need to worry about shards of wood flying in your face. No matter what you hit or how hard you swing them, they just won"t break. And they"re durable too, they won"t rot, crack, or splinter, or even fade. You can treat them as roughly as you choose. You needn"t worry about dirt or the weather affecting them either since they"re impervious to the elements and clean up with soap and water. Try that with a wood bat and you might damage it.They"re versatile too. Like any other baseball bat, croquet mallet, golf club or hockey stick, they can be used in an emergency, as an extremely effective self-defense tool. You can keep one behind the front door, under the bed, or in a car trunk and forget about it until you need it. They can be used as game bats, practice bats, warm-up bats, loaner bats, inclement weather bats, school or league bats or kid"s bats. They can also serve as a cross over trainers to develop strength, agility and eye hand coordination for those studying Western Saber Fencing, Kendo, Kenjitsu, Filipino Stick and Sword Fighting and Chinese martial arts.
