For many welders, having a finger design that works best for them makes all the difference in the world. For some TIG welders, they swear by a seamless index finger as it provides a better feel for the filling wire. Some MIG welders like the seamless feel on the trigger.
A flat seam with a double-stitched index finger is common on many Drivers and TrueFit® gloves. These are hard working gloves that are subjected to some pretty punishing conditions. These gloves are commonly used in construction, fabrication, wind energy, demolition or salvage, and anywhere hard-working hands need protection. The double stitching provides added strength in a high wear, vulnerable area.
