I am impressed with this set for the quality of the material, the knurled handle design, the precision workmanship, the durability, the shot peening and the ease of adjustment thanks to the quality threading. The ribbed design of the handles not only provides a secure grip, but also adds strength to the base material. I think it's head and shoulders above anything I've ever owned and in my opinion the engineering team that came up with this is just brilliant. The jaws of this entire set are strong, durable and rarely bend or deform during use. I'm also impressed with the quality of the springs, the rivets and the smoothness of the rolled stitching. The knurling on the adjustment knobs is also better than most. This is a professionally made, high quality set and I expect it to last a lifetime.
