If you ever need to bend a piece of metal, to make a clamp, for instance, you can achieve a somewhat-functional bend with a vise and pliers — but it takes too long and looks like crap. A better solution, the Veritas metal bender slips over most bench vise jaws to create bends between 180° and 90°.
The high-strength, cast iron die and v-block will bend up to 1/8″-thick mild steel. Veritas embeds 1/2″ rare earth magnets into each 3″ long by 1-1/8″ wide block to hold them securely on your vise jaws. Besides bending angles, the male die by itself in a vise will hold concave parts, and with the v-block alone you can securely clamp circular stock.
This cool little vise accessory runs only $19 at Lee Valley.
