Flat Sof-swords are the same technology as our round Sof-Stx, but we cut them flat to be more realistic. As far as we know, we are the only US based company making the flat swords. We use the 1/2" foam w/ 1" pads on the tips for realistic thrusting, and come with both a Hollow Core - a bit of flex, and a reinforced Hickory core for more rigidity.
These are great for both training and sparring! Fun for any age!
