The Many Uses of The Shuber BladesThe Shuber Blades are a flexible accessory to protect your playing cards. Two stainless steel blades together with a special rubber band secure your cards regardless of if you want to protect one card or more than a regular deck of cards.
You can not only protect your cards, but you can also use the Shuber Blades to build a pocket card press. Take two large paper clips of the kind shown below.
Clip one on each short end of the deck enclosed in the Shuber Blades. Then remove the wire handles from the clips.
The blades evenly distribute the clamping force of the clips, pressing the cards flat against each other and against the steel blades. You can also use just one clip and stand the deck upright on its short end.
Caring for your Shuber BladesWhen you get your Shuber Blades check the edges. It can happen that the edges are a little bit sharper than you like. Sharp edges will also reduce the lifetime of your rubber bands. Take a file, polishing paper or steel wool and rub it against the edges until they feel the way you like them.
The blades themselves are very robust. You can use any stainless steel cleaner to make them shine as new. I personally like to have a little patina develop on mine. The rubber band will at some point fail. Rubber does age and will get brittle after a few years. And even earlier, depending on how you use and stretch them, they can break. We do sell replacement packs of five, but you can certainly use other bands or even clips as shown above.
