Welcome to STEEL SQWIRE, LLC. Steel Sqwire is a game accessory manufacturer. We enjoy making products that allow the games you play to be more enjoyable.
STEEL SQWIRE, LLC was founded in July 2004 by designer, innovator and entrepreneur Jeff Petersen. STEEL SQWIRE's initial product was developed based on the need to provide Dungeon and Dragon® players with a faster and cleaner playing environment. Jeff's wife, Stephanie, was never really fond of having her husband come home after an evening of gaming with blue fingers from casting spells and/or throwing fireballs with a wet erase marker during an adventure. This complaint led to the creation of the Spell Radius packages by STEEL SQWIRE.
If you are new to the game and not sure why fingers would be blue or what a spell radius is, click here for a full description.
You may ask, why wire? If you've been a gamer for a while you may have tried cardboard, plastic, pipe cleaners or hangers for your spell templates. Well, Jeff had these same thoughts and made the sturdiness of the product and the ability to place the template around the miniatures in play his highest priority. He tested many types of materials and found that for gamers only the strongest would do and as a result the STEEL template was born. A wire former/bender out east cheerfully fulfilled our request without a thought as to how we were going to utilize these crazy shapes.
This may lead you to now ask, why Squire? All of our products are designed to aid gamers. We don't make games, but rather create products to make your game more fun. In Chivalry, the Squire is an aid to a Knight. He is there to provide the Knight with what he needs to perform at his best. Our hope is that our products give you that same feel and provide you with what you need in your adventures.
