With great Laser Power comes great responibility...to make as many cool things as we can think of! These bending jigs are neat because they have parallel stepped sides so you can get that perfect 90° bend on every resistor! (Ha! Take that, injection-molded plastic trapezoids!) And in case you don't already have the two most important resistor equations engraved in your head, we've engraved them on the front. The Benders come in 1/4W or 1/8W sizes (1/2W and 1W coming soon) and you can choose from MDF or Cherry (I know, super fancy). You can also use these to bend your own custom breadboard jumpers!
